By default, which VLAN is the Cisco management VLAN?
Cisco uses VLAN1 as the default management VLAN.
All ports are automatically assigned to VLAN1. Cisco Discovery Protocol (CDP) and VLAN Trunking Protocol (VTP) advertisements are transmitted on VLAN1. VLAN1 is the management VLAN and is used for administration. It cannot be deleted or pruned from a trunk line.
VLAN Ids that are implemented can vary based on whether the trunk implementation is Cisco’s Inter-Switch Link (ISL) or the IEEE 802.1Q standard.
The following is a summary of the VLAN IDs:
0 and 4095 – Reserved
1 – Cisco default management
2-1001 – Available for Ethernet VLANs
1002-1005 – Defaults for FDDI and Token Ring VLANs
1006-4094 – Extended range available for Ethernet VLANs (802.1Q only)
