TCAM entries in FWS devices
TCAM entries in FWS devices
The size of the TCAM in FWS devices is limited to 1024 routing entries. When this limit is reached,
the following warning message is displayed.
No free TCAM entry available. System will be unstable. Please reboot system.
At the same time, the following syslog message is generated.
System: No Free Tcam Entry available. System will be unstable.
You must reboot the device when you see these messages.
Adding a static IP route
To add a static IP route, enter a command such as the following at the global CONFIG level of the
CLI.
Brocade(config)#ip route 209.157.2.0 255.255.255.0 192.168.2.1
This command adds a static IP route to the 209.157.2.x/24 subnet.
Syntax: [no] ip route <dest-ip-addr> <dest-mask> <next-hop-ip-addr> [<metric>] [tag <num>]
or
Syntax: [no] ip route <dest-ip-addr>/<mask-bits> <next-hop-ip-addr> [<metric>] [tag <num>]
On FastIron X Series devices, you can add up to 2048 static IP routes.
The <dest-ip-addr> variable is the route destination. The <dest-mask> variable is the network
mask for the route destination IP address. Alternatively, you can specify the network mask
information by entering a forward slash followed by the number of bits in the network mask. For
example, you can enter 192.0.0.0 255.255.255.0 as 192.0.0.0/.24. To configure a default route,
enter 0.0.0.0 for <dest-ip-addr> and 0.0.0.0 for <dest-mask> (or 0 for the <mask-bits> variable if
you specify the address in CIDR format). Specify the IP address of the default gateway using the
<next-hop-ip-addr> variable.
The <next-hop-ip-addr> variable is the IP address of the next hop router (gateway) for the route.
The <metric> variable specifies the cost of the route and can be a number from 1 through 16. The
default is 1. The metric is used by RIP. If you do not enable RIP, the metric is not used.
The tag <num> parameter specifies the tag value of the route. The possible value is from 0 through
4294967295. The default value is 0.
NOTE
You cannot specify null0 or another interface as the next hop in the base Layer 3 image.
