Configuring route-table profiles

The following table describes the available command options (keywords) to optimize route profiles, available under the route-table keyword in turn under the hardware-profile command (refer to the Network OS Command Reference).
Table 9 Options for optimizing route-table profiles
Keyword Optimizes resources for . . .
default Basic IPv4/IPv6 dual-stack operations
ipv4-max-arp Maximum number of IPv4 ARP entries
ipv4-max-route Maximum number of IPv4 routes
ipv4-min-v6 IPv4 routes in dual-stack configurations
ipv6-max-nd Maximum number of IPv6 Neighbor Discovery entries
ipv6-max-route Maximum number of IPv6 routes
kap Keep-alive profiles
maximum_paths Maximum number of ECMP paths (8, 16, 32)
openflow OpenFlow support
route-table Route profiles
With the current release, two new keywords have been added, available under the route-table profile type.
  • The maximum-paths keyword allows the user to configure the maximum number of ECMP paths. This keyword is optional. If not selected, the maximum-path configuration remains unchanged. The valid values are 8, 16, and 32, with 8 the initial default. (Once the latter value is changed, it must be reentered explicitly, which is different from previous releases.) As with other changes to the hardware profile, the switch must be rebooted for changes to take effect.
  • The openflow keyword allows the user to enable or disable support for the OpenFLow feature in the route-table profile. This keyword is optional. If it is not used, the OpenFlow profile setting is unchanged. This keyword is also available under the TCAM profile. (Refer to the following section.)

The following example specifies maximum paths and disables OpenFlow in the TCAM profile, and then confirms the configuration.

device(config-rbridge-id-67)# hardware-profile route-table ipv4-max-arp ?
Possible completions:
  maximum_paths   Maximum number of load-sharing paths
  openflow        Enable/disable openflow support
  <cr>
device(config-rbridge-id-67)# hardware-profile route-table ipv4-max-arp maximum-path 16
%Warning: To activate the new profile config, please run 'reload system' on the target switch.

device# show running-config rbridge-id hardware-profile
rbridge-id 67
 hardware-profile tcam default
 hardware-profile route-table ipv4-max-arp  maximum-path 16 openflow off
 hardware-profile kap default

The following example selects a route-table profile to optimize resources for the maximum number of IPv6 Neighbor Discovery entries:

switch(config)# rbridge-id 10
switch(config-rbridge-id-10)# hardware-profile route-table ipv6-max-nd
%Warning: To activate the new profile config, please run 'reload system' on the target switch.
NOTE
When you use the hardware-profile route-table ? command to see the available options, the currently applied hardware profile is at the top of the list and is enclosed by square brackets ([ ]).
