Monitoring 802.3ad Link Aggregation

Use the transmitter keyword to enable or disable the transmitter when in redundant
mode.
Disabling the transmitter enables the remote end of the redundant link to also be in
the operational Down state, which might be a requirement for third-party equipment
when supporting redundancy over LAG.
Enabling the transmitter provides for a quick LAG failover in the event one of the
non-redundant links in the LAG fail. This is particularly true when LACP has been
enabled on the LAG, because it can take several seconds for LACP to converge on
a link.
Use the auto-revert keyword to instruct the redundant link to revert back to redundant
mode when the failed link becomes active again. By default, auto-revert is disabled.
Example 1—Specifies that the Gigabit Ethernet interface in slot 4, port 0 is a redundant
member interface
host1(config-if)#redundant-port gigabitEthernet 4/0
Example 2—Specifies that the Gigabit Ethernet interface in slot 1, port 1 is a redundant
member interface with a packet sampling delay of 500 ms
host1(config-if)#redundant-port gigabitEthernet 1/1 packet-sampling delay 500
Use the no version to disable the redundant status of the member interface or disable
the specified redundancy setting for the member.
See redundant-port.
Use to force the specified member interface to fail over when more than one active
member exists.
Example
host1(config-if)#redundant-port gigabitEthernet 4/0 force-failover
There is no no version.
See redundant-port force-failover.
This section explains how to use the show commands to display the characteristics and
the configured settings for 802.3ad link aggregation.
NOTE: The E120 and E320 routers output for monitor and show commands is identical
to output from other E Series routers, except that the E120 and E320 routers output
also includes information about the adapter identifier in the interface specifier
(slot/adapter/port).
