port-channel linktrap
This command enables link trap notifications for the port-channel (LAG). The interface is a
logical slot/port for a configured port-channel. The option all enables link trap
notifications for all the configured port-channels.
Default
Format port-channel linktrap {<slot/port> | lag <lag-group-id> | all}
Mode
no port-channel linktrap
This command disables link trap notifications for the port-channel (LAG). The interface is a
logical slot and port for a configured port-channel. The option all disables link trap
notifications for all the configured port-channels.
Format no port-channel linktrap {<logical slot/port> | all}
Mode
port-channel load-balance
This command selects the load-balancing option used on a port-channel (LAG). Traffic is
balanced on a port-channel (LAG) by selecting one of the links in the channel over which to
transmit specific packets. The link is selected by creating a binary pattern from selected fields
in a packet, and associating that pattern with a particular link.
Load-balancing is not supported on every device. The range of options for load-balancing
can vary per device. The managed switch also supports enhanced hashing mode, which has
the following advantages:
• MODULO-N (where N is the number of active link members in a LAG) operation based on
the number of ports in the LAG
• Packet attributes selection based on the packet type: For L2 packets, source and
destination MAC address are used for hash computation. For L3 packets, source IP,
destination IP address, TCP/UDP ports are used.
• Non-Unicast traffic and unicast traffic is hashed using a common hash algorithm
• Excellent load balancing performance.
Default
Format port-channel load-balance { 1 | 2 | 3 | 4 | 5 | 6 | 7} {<slot/port>
|<all>}
