Cisco IP Phone and lost packets
Posted on 2013-11-04
I have an issue that I can't quite wrap my head around. I have been getting complaints about voice quality issues the past few weeks. If I http to a users phone who is complaining, and look at the Rcvr Lost Packets its at like 50. This phone is plugged into a Cisco 6513 switch. This switch has 8 switch blades and I get Rcvr packet loss on all blades I plug the IP Phones into. I wouldn't think all 8 blades are bad. For test purposes, I grabbed a cisco 3560G and plugged two IP phones in, and the Rcvr Lost Packets has been at 0 for a couple hours now. The switchport on the 6513 that I'm seeing dropped packets on looks like the following:
no ip address
switchport mode access
The 3560G that I'm testing with basically has no configuration other than an IP and Gateway: Ports have not configuration, just default.
Any ideas? I have no clue what is causing this.
