I haven't been around much lately or had time to read much, but I still like to post odd tid-bits that I run into. Cisco 7960 IP phones (probably all of the 79xx line) can run 100mbit full-duplex. However, they will not run full-duplex on a Catalyst 4006 48-port inline power blades *if* you set the port to 100/full, disabling auto-negotiation. Does this occur with other switches? No time to troubleshoot it. What I did observe is that the switch will report a duplex mismatch, and the phone itself will show running half-duplex. However, simply setting the Cat4K port back to speed auto allows the phone to run 100/full (most be something in its limited capacity where it must negotiate, and if it doesn't it just falls back to half-duplex). Here's a Cisco URL confirming they run 100/full (which is what prompted me to set it back to auto): http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/7900/admingd/7900set.htm TTFN, Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=8989&t=8989 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
