snCamUsageL3Size
Module: FOUNDRY-SN-CAM-MIB
OID (symbolic): FOUNDRY-SN-CAM-MIB::snCamUsageL3Size
OID (numeric): 1.3.6.1.4.1.1991.1.14.1.1.2.1.1.5
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The effective CAM size for this layer 3 traffic entry. For ipv4 traffic, each unit is 4 bytes. For ipv4vpn, each unit is 8 bytes. For ipv6, each unit is 16 bytes.
What is snCamUsageL3Size?
This value reports the total effective CAM capacity, in entries, allocated for a specific layer 3 traffic type (such as IPv4, IPv4 VPN, or IPv6) on a given linecard's network processor. Administrators use this alongside snCamUsageL3Free to calculate how much of the hardware forwarding table capacity is provisioned for that traffic type. For example, an snCamUsageL3Size of 32768 for an ipv4 entry means that supernet slot can hold up to 32,768 IPv4 route entries.
