Figure 61. SHOW GLC Command
The possible group status are:
 Up - The upstream and downstream ports are forwarding traffic
because the upstream ports have links to network nodes.
 Down - Group link control has disabled the downstream ports to
prevent them from forwarding traffic because the upstream ports do
not have links to network nodes.
 Suspended - The group is incomplete, lacking either an upstream port
or a downstream port. A downstream port in an incomplete group
forwards traffic normally.
