Foundry Configuration Guide for the FESX, FSX, and FWSX
16 - 66 © Foundry Networks, Inc. December 2005
The <ip-addr> and <ip-mask> parameters let you restrict the display to entries for a specific IP address and
network mask. Specify the IP address masks in standard decimal mask format (for example, 255.255.0.0).
NOTE: The <ip-mask> parameter and <mask> parameter perform different operations. The <ip-mask>
parameter specifies the network mask for a specific IP address, whereas the <mask> parameter provides a filter
for displaying multiple MAC addresses that have specific values in common.
The <num> parameter lets you display the table beginning with a specific entry number.
Displaying the Forwarding Cache
To display the IP forwarding cache, enter the following command at any CLI level:
Syntax: show ip cache [<ip-addr>] | [<num>]
The <ip-addr> parameter displays the cache entry for the specified IP address.
The <num> parameter displays the cache beginning with the row following the number you enter. For example, to
begin displaying the cache at row 10, enter the following command: show ip cache 9.
