Chapter 22: Group Link Control Commands
428 Section II: Advanced Operations
ADD GLC
Syntax
add glc upstream|downstream group port
Parameters
upstream| Specifies whether a port is to be an upstream port or a
downstream downstream port of a group.
group Specifies a group for a port. You can specify only one
group and the group must already exist. The range is 1 to
8.
port Specifies a port to add to a group. You can specify more
than one port.
Description
This command is used to add upstream and downstream ports to groups
for group link control. Here are the guidelines:
 A group must already exist before you can add ports to it. To create
groups, refer to “CREATE GLC” on page 430.
 You can add either upstream ports or downstream ports to a group,
but not both in the same command.
 Adding a port to a group does not change its other group memberships
because ports can belong to more than one group at a time. To move
a port to a different group, you must remove it from its current group
assignment before or after adding it to its new group.
 A group that does not have any upstream ports is placed in a
suspended state. Downstream ports are permitted to forward traffic
normally.
 A port stops forwarding network traffic if you add it as a downstream
port to a group that does not have links on the upstream ports.
Examples
This command adds ports 5 and 6 as downstream ports of group 1:
add glc downstream 1 5,6
This command adds port 15 as an upstream port of group 2:
add glc downstream 2 15
