Cisco Catalyst 6509 - Show etherchannel summary

[TCCS TCS]

Hello Experts,

When I run the show IP protocol command on Agg switch which are in VSS I see below output. Can you help us understand why some port-channel show (RU) and some show (SU). What does the output mean. Sorry being new to Cisco 6509 thought to check with experts. Please help

hi

RU is a routed port-channel with an ip address layer 3 port-channel

SU is a layer 2 switched / trunked or access port-channel with no ip address

actually it should show you when you run that command

example

xxxxxxxx#sh etherchannel summary
Flags:  D - down        P - bundled in port-channel
        I - stand-alone s - suspended
        H - Hot-standby (LACP only)

        U - in use      N - not in use, no aggregation
        f - failed to allocate aggregator

        M - not in use, no aggregation due to minimum links not met
        m - not in use, port not aggregated due to minimum links not met
        u - unsuitable for bundling
        d - default port

        w - waiting to be aggregated
Number of channel-groups in use: 17
