You can configure 246 VLANs on the Web Switching Module using VLAN IDs 1- 4092. During default configuration, VLANs 1, 2, and 4093 are created automatically. For more information, see About ports.

You can change the port memberships or VLAN IDs for VLANs 1 and 2 but not VLAN 4093. If VLANs 1 and 2 are already configured in your network, consider whether Web Switching Module traffic should use VLANs 1 and 2. If so, no change is necessary. If not, assign other VLAN IDs for the Web Switching Module traffic after inserting the module.


VLAN	Restriction
VLAN 1	By default, VLAN 1 is assigned to Front-facing ports 1-4, Rear-facing ports 7 and 8, and BFM ports 3 and 4. VLAN 1 cannot be deleted on either the WSM or the 8600 series switch.
VLAN 2	By default, VLAN 2 is assigned to Rear-facing ports 5 and 6 and BFM ports 1 and 2. You cannot delete VLAN 2 on the Web Switching Module; but you can delete it on the 8600 series switch.
VLAN 4093	VLAN 4093 is reserved for management of the Web Switching Module's connection to the Passport backplane. VLAN 4093 is permanently configured on the trunked Rear-facing ports 7 and 8 and BFM ports 3 and 4 and cannot be modified or deleted. If VLAN 4093 is already configured on your network, you must change that VLAN to use another VLAN ID before inserting the Web Switching Module.

Note: All ports must belong to at least one VLAN. Any port which is removed from a VLAN, and which is not a member of any other VLAN, is automatically added to default VLAN #1. You cannot remove a port from VLAN #1 if the port has no membership in any other VLAN. Also, you cannot add a port to more than one VLAN unless the port has VLAN tagging turned on. See Configuring VLAN tagging.
