The following rules apply to all 8000 Series switch VLANs:
|
- In addition to the default VLAN, the 8100 Series switch can support up to 2000 VLANs; and the 8600 Series switch can support up to 1980 VLANs. VLAN IDs range from 1 to 4094.
|
- If you enable tagging on a port that is in a VLAN, the spanning tree group configuration for that port is lost. To preserve VLAN assignment of ports, enable tagging on the ports before you assign the ports to VLANs.
|
- A tagged port can belong to multiple VLANs and multiple spanning tree groups. When a tagged port belongs to multiple spanning tree groups, the BPDUs are tagged for all spanning tree groups except for spanning tree group 1. Under the default configuration, the default spanning tree group is number 1.
|
- An untagged port can belong to one and only one port-based VLAN. A port in a port-based VLAN can belong to other policy-based VLANs.
|
- An untagged port can belong to one and only one policy-based VLAN for a given protocol. For example, a port can belong to only one policy-based VLAN where the policy is IPX802dot2 protocol.

|
In addition to the rules that apply to all 8000 Series switch VLANs, the following rules apply to 8600 modules only:
|
- For every VLAN with MultiLink Trunking that you create, you reduce by eight the number of available VLANs.
|
- A VLAN cannot span multiple spanning tree groups; that is, the ports in the VLAN must all be within one spanning tree group. Spanning tree group IDs can range in value from 1 to 25.
|
- A frame's VLAN membership is determined by the following order of precedence: VLAN ID, then source MAC-based VLAN, then IP subnet-based VLAN, then protocol-based VLAN, then port-based VLAN.
|
- The IP subnet-based VLAN should not be assigned to a transit network, a network routing to a bridged subnet.
|
|
In addition to the rules that apply to all 8000 Series switch VLANs, this rule applies to 8100 modules only:
|
- A frame's membership in a VLAN is determined in the following order of precedence:
