Checking Network Devices and Testing Connectivity : Configuring IP addresses

Configuring IP addresses
You must configure at least one IP address using the serial connection to the CLI before you can manage the system using the other management interfaces.
Brocade devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain Routing (CIDR) network prefix masks.
To enter a classical network mask, enter the mask in IP address format. For example, enter
“209.157.22.99 255.255.255.0” for an IP address with a Class-C subnet mask.
To enter a prefix number for a network mask, enter a forward slash ( / ) and the number of bits in the mask immediately after the IP address. For example, enter “209.157.22.99/24” for an IP address that has a network mask with 24 significant (“mask”) bits.
By default, the CLI displays network masks in classical IP address format (example: 255.255.255.0). You can change the display to the prefix format. See the FastIron Configuration Guide.
Devices running Layer 2 software
Use the following procedure to configure an IP Address on a device running Layer 2 software.
1.
Brocade> enable
2.
Enter the following command at the Privileged EXEC level prompt (for example, Brocade FCX#), then press Enter. This command erases the factory test configuration if still present:
Brocade# erase startup-config
* CAUTION: Use the erase startup-config command only for new systems. If you enter this command on a system you have already configured, the command erases the configuration. If you accidentally do erase the configuration on a configured system, enter the write memory command to save the running configuration to the startup-config file.
3.
Brocade# configure terminal (Privileged EXEC Level)
Brocade(config)# (Global CONFIG Level)
4.
Brocade(config)# ip address 192.22.3.44 255.255.255.0
5.
Brocade(config)# ip default-gateway 192.22.3.1
NOTE: You do not need to assign a default gateway address for single subnet networks.
Syntax:
enable [<password>]
Syntax:
Syntax:
[no] ip address <ip-addr> <ip-mask>
or
Syntax:
[no] ip address <ip-addr>/<mask-bits>
Syntax:
Devices running Layer 3 software
Before attaching equipment to a Brocade Layer 3 Switch, you must assign an interface IP address to the subnet on which the router will be located. You must use the serial connection to assign the first IP address. For subsequent addresses, you also can use the CLI through Telnet or the Web management interface.
By default, you can configure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-interface table.
The following procedure shows how to add an IP address and mask to a router port.
1.
Brocade> enable
2.
Enter the following command at the CLI Privileged EXEC level prompt, then press Enter. This command erases the factory test configuration if still present:
Brocade# erase startup-config
CAUTION: Use the erase startup-config command only for new systems. If you enter this command on a system you have already configured, the command erases the configuration. If you accidentally do erase the configuration on a configured system, enter the write memory command to save the running configuration to the startup-config file.
3.
Brocade# configure terminal Privileged EXEC Level
Brocade(config)# Global CONFIG Level
4.
Brocade(config)# int e 2
Brocade(config-if-e1000-2)# ip address 192.22.3.44 255.255.255.0
NOTE: You can use the syntax ip address <ip-addr>/<mask-bits> if you know the subnet mask length. In the above example, you could enter ip address 192.22.3.44/24.
Syntax:
enable [<password>]
Syntax:
Syntax:
[no] ip address <ip-addr> <ip-mask> [secondary]
or
Syntax:
[no] ip address <ip-addr>/<mask-bits> [secondary]
Use the secondary parameter if you have already configured an IP address within the same subnet on the interface.
Configuring IP parameters for devices running Layer 3 software
This section describes how to configure IP parameters for devices running Layer 3 software.
Configuring IP addresses
You can configure an IP address on the following types of Layer 3 switch interfaces:
By default, you can have up to 24 IP addresses on each interface, but you can increase this number to 128 IP addresses.
NOTE: Once you configure a virtual routing interface on a VLAN, you cannot configure Layer 3 interface parameters on individual ports in the VLAN. Instead, you must configure the parameters on the virtual routing interface itself.
Brocade devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain Routing (CIDR) network prefix masks.
To enter a classical network mask, enter the mask in IP address format. For example, enter
“209.157.22.99 255.255.255.0” for an IP address with a Class-C subnet mask.
To enter a prefix network mask, enter a forward slash ( / ) and the number of bits in the mask immediately after the IP address. For example, enter “209.157.22.99/24” for an IP address that has a network mask with 24 significant bits (ones).
By default, the CLI displays network masks in classical IP address format (for example: 255.255.255.0). You can change the display to prefix format.
Assigning an IP address to an Ethernet port
Enter the following commands to assign an IP address to port 1/1/1.
Brocade(config)# interface ethernet 1/1/1
Brocade(config-if-1/1/1)# ip address 192.45.6.1 255.255.255.0
 
NOTE: You also can enter the IP address and mask in CIDR format, as follows:
Brocade(config-if-1/1/1)# ip address 192.45.6.1/24
Syntax:
[no] ip address <ip-addr> <ip-mask>
or
Syntax:
[no] ip address <ip-addr>/<mask-bits>
Assigning an IP address to a loopback interface
Loopback interfaces are always up, regardless of the states of physical interfaces. They can add stability to the network because they are not subject to route flap problems that can occur due to unstable links between a Layer 3 Switch and other devices. You can configure up to four loopback interfaces on a Layer 3 switch.
You can add up to 24 IP addresses to each loopback interface.
NOTE: If you configure the Brocade switch to use a loopback interface to communicate with a BGP4 neighbor, you must also configure a loopback interface on the neighbor and configure the neighbor to use that loopback interface to communicate with theBrocade switch.
To add a loopback interface, enter commands such as those shown in the following example:
Brocade(config)# exit
Brocade(config)# int loopback 1
Brocade(config-lbif-1)# ip address 10.0.0.1/24
Syntax:
The <num> parameter specifies the virtual interface number. You can specify from 1 to the maximum number of virtual interfaces supported on the device. To display the maximum number of virtual interfaces supported on the device, enter the show default values command. The maximum is listed in the System Parameters section, in the Current column of the virtual-interface row.
Assigning an IP address to a virtual routing interface
A virtual interface is a logical port associated with a Layer 3 Virtual LAN (VLAN) configured on a Layer 3 switch. You can configure routing parameters on the virtual interface to enable the Layer 3 switch to route protocol traffic from one Layer 3 VLAN to the other, without using an external router.
This section describes how to configure an IP address on a virtual interface.
NOTE: The switch uses the lowest MAC address on the device (the MAC address of port 1 or 1/1/1) as the MAC address for all ports within all virtual interfaces you configure on the device.
Enter commands similar to the following to add a virtual interface to a VLAN and configure an IP address on the interface.
Brocade(config)# vlan 2 name IP-Subnet_1.1.2.1/24
Brocade(config-vlan-2)# untag 1/1/1 to 1/1/4
Brocade(config-vlan-2)# router-interface ve1
Brocade(config-vlan-2)# interface ve1
Brocade(config-vif-1)# ip address 1.1.2.1/24
The first two commands in this example create a Layer 3 protocol-based VLAN name “IP-Subnet_1.1.2.1/24” and add a range of untagged ports to the VLAN. The router-interface command creates virtual interface 1 as the routing interface for the VLAN. The last two commands change to the interface configuration level for the virtual interface and assign an IP address to the interface.
Syntax:
Syntax:
Deleting an IP address
Enter a command similar to the following to delete an IP address.
Brocade(config-if-1/1/1)# no ip address 1.1.2.1
This command deletes IP address 1.1.2.1. You do not need to enter the subnet mask.
To delete all IP addresses from an interface, enter the following command:
Brocade(config-if-1/1/1)# no ip address *
Syntax:
no ip address <ip-addr> | *
Connecting network devices
Brocade devices support connections to other vendors’ routers, switches, and hubs, as well other Brocade devices.
Connectors.
For port pinouts, refer to “Pinouts and signalling”.
Cable specifications
Refer to “Cable specifications” for cable lengths and types.
Connecting to Ethernet or fast Ethernet hubs
For copper connections to Ethernet hubs, a 10/100BaseTX or 1000BaseT switch, or another Brocade device, a crossover cable is required (Figure 37 and Figure 38). If the hub is equipped with an uplink port, it will require a straight-through cable instead of a crossover cable.
NOTE: The 802.3ab standard (automatic MDI or MDIX detection) calls for automatic negotiation of the connection between two 1000Base-T ports. In this case a straight-through cable may work just as well as a crossover cable. For more information about this feature, see the FastIron Configuration Guide.
Figure 37 UTP crossover cable
 
Figure 38 Straight-through cable
 
Connecting to workstations, servers, or routers
Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or routers using network interface cards (NICs).
Fiber cabling is required for direct attachment to Gigabit NICs or switches and routers through fiber ports. Refer to “Connecting a network device to a fiber port”.
Automatic MDI or MDIX detection
All 10/100 and Gbps Ethernet Copper ports on the devices support automatic Media Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This feature is enabled on all 10/100 and Gigabit copper ports by default. For each port, you can disable auto MDI or MDIX, designate the port as an MDI port, or designate the port as an MDIX port.
For more information about this feature and how configure it, refer to FastIron Configuration Guide.
Connecting a network device to a fiber port
For direct attachment from the device to a Gbps NIC, switch, or router, using a fiber optic transceiver, you will need fiber cabling with an LC connector.
To connect the device to another network device using a fiber port, you must do the following tasks:
The following sections describe these tasks.
Fiber Optic transceivers
Table 17 lists supported XFP transceivers (for stacking and non-stacking FCX models). Table 18 shows supported SFP and SFP+ transceivers. For information about cabling for transceivers, see Table 24.
 
 
 
Table 17
Supported XFP transceivers for Brocade FCX 624S, Brocade FCX 648S, Brocade FCX 624S-F, FCX648S-F, Brocade FCX 624S-HPOE, Brocade FCX 648S-HPOE
 
Table 18
Supported SFP transceivers for Brocade FCX 624-E, Brocade FCX 624-I, Brocade FCX 648-E, Brocade FCX 648-I
Installing a transceiver
You can install a new transceiver in an XFP, SFP, or SFP+ slot while the device is powered on and running.
While installing a transceiver, wear an ESD wrist strap with a plug for connection to a metal surface.
NOTE: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.
* CAUTION: All fiber optic interfaces use Class 1 lasers.
Use the following setps to install a transceiver.

Cabling a fiber optic transceiver
Use the following steps to cable a fiber optic transceiver.
1.
2.
Before cabling a fiber optic transceiver, Brocade strongly recommends cleaning the cable connectors and the port connectors. For more information, refer to “Cleaning the fiber optic connectors”.
3.
4.
Observe the link and active LEDs to determine if the network connections are functioning properly. For more information about the LED indicators, refer to Table 19.
Cleaning the fiber optic connectors
To avoid problems with the connection between the fiber optic transceiver (SFP, SFP+, or mini-GBIC) and the fiber cable connectors, Brocade strongly recommends cleaning both connectors each time you disconnect and reconnect them. Dust can accumulate in the connectors and cause problems such as reducing the optic launch power.
To clean the fiber cable connectors, Brocade recommends using a fiber optic reel-type cleaner. You can purchase this type of cleaner from the following Website:
http://www.fisfiber.com/Home_Page.asp
When not using an SFP connector, make sure to keep the protective covering in place.
