Format show port-channel
Mode Privileged EXEC
Static Capability whether the device has static capability enabled.
Port-channel/LAG Summary:
Lag Name The name of the lag.
Link State Indicates whether the Link is up or down.
Mbr Ports A listing of the ports that are members of this lag, in slot.port notation.
Active Ports A listing of ports that are actively participating in the LAG.
Spanning Tree (STP) Commands
This chapter provides a detailed explanation of the Spanning Tree commands. The commands are
divided into two functional groups:
• Show commands display switch settings, statistics, and other information.
• Configuration commands configure features and options of the switch. For every
configuration command, there is a show command that displays the configuration setting.
Note: The software platform STP default mode is IEEE 802.1s, but the legacy IEEE 802.1D mode
is available. To change to the legacy IEEE 802.1D mode, set the STP operational mode to
disabled, then enable the IEEE 802.1D mode from the source code. Recompile the software to
operationally enable the IEEE 802.1D mode. With the IEEE 802.1D mode operationally enabled,
the rapid configuration and multiple instances features are not available. If the rapid configuration
and multiple instances capabilities are required, use the IEEE 802.1s mode which is compatible
with the legacy IEEE 802.1D standard.
Note: STP is disabled by default. To enable STP for the device See “spanning-tree” on page 119.
However, this command does not enable STP on any of the device’s interfaces. To enable STP for
a specific interface See “spanning-tree port mode” on page 127. To enable STP for all the
interfaces See “spanning-tree port mode all” on page 127.
spanning-tree
This command sets the STP mode for a specific port-channel (LAG). This is the value specified
for STP Mode on the Port Configuration Menu. 802.1D mode is the default.
