Note #1

You can set up 4093 VLAN during stacking.

Note #2

If the optional license (port number extension) is set, the capacity is the same as AX3660S-24S8XW.

Note #3

If the optional license (port number extension) is set, the capacity is the same as AX3660S-48X4QW.

We recommend that you configure no more than 1024 VLANs. In a stack configuration, the recommended number of VLANs is no more than 1024 divided by the number of units that make up the stack (for a configuration of two units, the recommended number of VLANs is 512 or fewer).

The total number of VLANs across all ports on the switch is the number of VLANs configured on each port added together for all the ports on the switch. For example, in a 24-port switch, if 2000 VLANs are configured on ports 1 to 10, and one VLAN is configured on ports 11 to 24, the total per-port VLANs per switch will be 20014. Note that even ports belonging to a channel group are calculated based on the number of VLAN set for the port, rather than grouped by the channel group. If the total exceeds the capacity limit, CPU usage will increase, response to configuration commands and operation commands will be slower, and commands might fail to execute. Even in a stack configuration, the total number of VLANs per port in the switch is equal to the supported number for a single switch in the entire stack regardless of the number of units that make up the stack.

(1) Protocol VLAN

A protocol VLAN identifies protocols based on the values of the Ethernet-Type, LLC SAP, and SNAP type fields in an Ethernet frame. The following tables describe the capacity limits for configuring a protocol VLAN.

(4) Tag transformation

The following table describes the number of tag translation information entries that can be configured. If Tag translation is set for a channel group, entries are consumed for each port that belongs to the channel group.
