Displaying and Searching the L3 Forwarding Cache for an Entry
Web Agent Procedure
You can display and search the Layer 3 Forwarding Cache for an entry using the web agent, To display the contents of the L3 forwarding Cache, you can use the search function to display:
- only the selected options,

Select the search criteria that you want to use to find more specific information on available routes from the Search By column.
For example, if you want to find all entries in the Forwarding Cache by a VLAN, you would select the VLAN from the Search By column, and select the appropriate VLAN from the pull-down menu. Figure 22-4 is the actual display results from a Forwarding Cache search done by a VLAN.
