The preferred method is to set desirable mode at both ends of a link. The additional recommendation is to leave the silent/non-silent keyword at default - silent on Catalyst 6500/6000 and 4500/4000 switches, non-silent on Catalyst 5500/5000 fiber ports. </P><P>=============================================</P><P></P><P></P><P>From IOS doc </P><P>============================================</P><P>Cisco Configuration Recommendation for L2 Channels </P><P>Enable PAgP and use a setting of desirable-desirable on all EtherChannel links</P><P>=============================================</P><P></P><P>HTH</P><P></P><P>Jon</P><P></P></BODY></HTML> Wed, 31 Oct 2007 13:42:25 GMT https://community.cisco.com/t5/network-security/ehterchannel-question/m-p/837031#M1024032 Jon Marshall 2007-10-31T13:42:25Z
