Command History This table includes the following release-specific history entries:
Usage Guidelines The VLAN modes act as follows:
• vlan symmetric skip—Ignores tunnel.
• vlan a-symmetric skip—Ignores tunnel, asymmetric.
• vlan symmetric classify—VLAN tag as subscriber.
• When the tunneling information is ignored, the subscriber identification is the subscriber IP of the
IP packet carried inside the tunnel.
Use the symmetric skip form of the command to skip the VLAN header when flow classification does
not use the VLAN tag. VLAN tags are symmetric.
Use the a-symmetric skip form of the command to skip the VLAN header when flow classification does
not use the VLAN tag. VLAN tags are asymmetric. Note that this form of the command impacts
performance.
Use the symmetric classify form of the command when flow classification uses the VLAN tag. VLAN
tags are symmetric. Using VLAN classification is mutually exclusive with any other tunnel-based
classification.
Note The Cisco SCE 8000 supports a maximum of 4096 VLAN tags.
