Note A shared CAM board and non-shared CAM board can co-exist in the same switch router.
Figure 11-13 Shared CAM
There are always five P2MP VCs in the switch router:
• One VC for all Gigabit processor interfaces, with two leaves for each Gigabit processor interface.
• Four P2MP VCs for each Ethernet processor interface, one corresponding to each channel.
With shared CAM, Gigabit processor interface P2MP remains the same. However, for Ethernet processor
interfaces with shared CAM, only channel-0 leaf is created. Other channel leaves are not created. This
allows a mix of private, shared, and dual CAM interfaces in the switch router.
To determine what type of CAM is installed on your interface use the show hardware detail command
as shown in the following example:
