Port Channel Flag Details

All,

I created an etherchannel between a cat3750G and a cat6509. I ran a show etherchannel 5 detail and I noticed for my flags I got SC. Is this okay, I am wondering because I looked it up and it doesn't sound good but I could be reading it wrong. Thanks

Re: Port Channel Flag Details

Looks perfect , both are up , master in bundle and they see each and have negotiated the etherchannel properly . You can also do a show etherchannel summary to I believe which gives you a compact reading on the channel.
