VMAN Example
The follow example shows the steps to configure VMAN 1 on the Black Diamond 10808 switch shown
in Figure 7.
Figure 7: Sample VMAN configuration
The VMAN is from the building to port 1, slot 1 on the BD 10808 and from port 1, slot 6 on the BD
10808 to the BD 6808:
create vman vman_tunnel_1
configure vman vman_tunnel_1 tag 100
configure vman vman_tunnel_1 add port 1:1 untagged
configure vman vman_tunnel_1 add port 6:1 tagged
You can display the VMAN configuration by issuing the show vman command. You can also display
VMAN information, as well as all the VLANs, by issuing the
show port information detail display.
Guidelines for Configuring VMANs
The following are some guidelines for configuring VMANs:
• Duplicate customer’s MAC address ingressing from multiple VMAN ports may disrupt the port
learning association process in the switch.
• VMAN ports can belong to load-sharing groups. If any port in the load-sharing group is enabled for
VMAN, all ports in the group are automatically enabled to handle jumbo size frames. Also, VMAN
is automatically enabled on all ports of the untagged load-sharing group.
