cefAdjEncap
Module: CISCO-CEF-MIB
OID (symbolic): CISCO-CEF-MIB::cefAdjEncap
OID (numeric): 1.3.6.1.4.1.9.9.492.1.2.2.1.5
Node type: OBJECT-TYPE
Type: SnmpAdminString
Access: read-only
Description: The layer 2 encapsulation string to be used for sending the packet out using this adjacency.
What is cefAdjEncap?
This reports the actual Layer 2 encapsulation string, the pre-built frame header, that CEF prepends to packets sent out via this specific adjacency. Because this is the literal header CEF will apply at line rate, an admin debugging a specific forwarding path can read this object to verify the exact destination MAC address, VLAN tag, or other Layer 2 fields being used, rather than inferring them indirectly from routing tables. For an Ethernet adjacency, this object might contain the destination MAC address and EtherType bytes CEF prepends to every packet sent to that specific next hop.
Examples
