ciscoVdcFCoEVlansFirst2K
Module: CISCO-VDC-MIB
OID (symbolic): CISCO-VDC-MIB::ciscoVdcFCoEVlansFirst2K
OID (numeric): 1.3.6.1.4.1.9.9.774.1.5.2.1.1
Node type: OBJECT-TYPE
Type: Cisco2KVlanList
Access: read-write
Description: A string of octets containing one bit per VLAN for VLANs 0 to 2047 that are reserved for FCoE.
If the bit corresponding to a VLAN is set to '1', then the VLAN is reserved for FCoE. If the bit is set to '0', then the VLAN is not reserved for FCoE
What is ciscoVdcFCoEVlansFirst2K?
This read-write Cisco2KVlanList is a bitmap, one bit per VLAN, marking which VLANs from 0 to 2047 are reserved for FCoE traffic, with a set bit meaning the VLAN is reserved. An admin sets specific bits here to carve out the lower half of the VLAN space exclusively for Fibre Channel over Ethernet, keeping it separate from regular Ethernet VLANs. Setting the bit for VLAN 1000 in ciscoVdcFCoEVlansFirst2K reserves that VLAN so it can only carry FCoE storage traffic, not ordinary data traffic.
