Determining maximum static routes

You can modify the maximum number of static routes.
Note: Output examples in this section do not reflect system values for ICX devices. For example, the ICX 7150 default value for IPv4 static routes is 512, the minimum value is 64, and the maximum value is 512.

Perform these steps to check the maximum setting for static routes and to modify the value.

  1. Verify the current maximum setting for the device. 
    device# show default values
    The maximum number of static IP routes the system can retain is listed under System Parameters in the ip-static-route row as shown in the following example. 
    device# show default values
sys log buffers:50 mac age time:300 sec telnet sessions:5
ip arp age:10 min bootp relay max hops:4 ip ttl:64 hops
ip addr per intf:24

ip6-route-vrf        100     5120    100      100
device(config)#
  2. Enter global configuration mode. 
    device# configure terminal
  3. Specify a new maximum for IP static routes. 
    device(config)# system-max ip-static-route 4096
  4. Save the change and reload the device. 
    device(config)# write memory
device(config)# reload
  5. Verify the change with the show default values command.

The following example changes the system max value for IP static routes from 2048 to 4096. 

device# configure terminal
device(config)#
device(config)# show default values
sys log buffers:50 mac age time:300 sec telnet sessions:5
ip arp age:10 min bootp relay max hops:4 ip ttl:64 hops
ip addr per intf:24
