Configuring Interfaces

Bridging an Interface to a VLAN

To specify a VLAN and associate it with the specified Ethernet interface, use the bridge vlan command. Enter an integer from 1 to 4094 as the VLAN identifier. The default is 1. All interfaces are assigned to VLAN1 by default.

The following list defines the maximum number of VLANs supported by the specific CSS models:

•CSS 11501 and CSS 11503 - A maximum of 256 VLANs per CSS and 64 VLANs per port (FE or GE)

•CSS 11506 - A maximum of 512 VLANs per CSS and 64 VLANs per port (FE or GE)

When you specify the bridge vlan command, enter the word vlan in lowercase letters and include a space before the VLAN number (for example, vlan 2).

For example, to configure e1 to VLAN2 on the CSS 11501, enter:

(config-if[e1])# bridge vlan 2

The CSS Gigabit Ethernet and Fast Ethernet interface ports support trunking to multiple VLANs through the trunk command. In this configuration, use the trunk command for the Ethernet interface instead of the bridge vlan command (and the other associated bridge CLI commands).

To restore the default VLAN1 on the CSS 11501, enter:

(config-if[e7])# no bridge vlan

To display all interfaces and the VLANs to which they are configured, use the show circuit command. In the show circuit display, VLANs appear as VLAN (uppercase, with no space before the VLAN number). See the “Showing Circuits” section for information about the show circuits command.

Specifying VLAN Trunking for an Interface

To activate VLAN trunking for a CSS interface, use the trunk command. You specify all VLANs that include the specified port as part of the VLAN. The trunk command also converts the link in to a trunk link. Use the vlan command to specify the number of each VLAN to be associated with the Gigabit Ethernet or Fast Ethernet port. Enter an integer from 1 to 4094 as the VLAN identifier.
