Hi All,
I've got an issue with a customer, in which we've discovered a Speed and Duplex settings mis-match.
The G540 was locked to 100MB/Full Duplex but the LAN was set to Auto-Neg.
The customer is kicking off, saying that we've configured the G450 wrong and that Avaya now recommend on Gig interfaces that they be set to Auto-Neg. Avaya have produced the "Ethernet Link Guidelines for Avaya Aura Unified Communications Products" document, which does say that Gig interfaces should be set to Auto-Neg. But at the same time the abstract of the doc also says that:
"The new guideline for current and recent products is that both auto-negotiation and 100M/Full-duplex lock-down are acceptable practices to establish a reliable 100M/Full-duplex link between an Ethernet host and an Ethernet switch port. Auto-Negotiation is the preferred method and is an industry Best Practice."
So has anybody ever had this conversation with a customer?? How are you guys configuring the G450 ports??
My view is that as long as both ends of the link are configured the same, then you'll be fine.....
Also in the event of a speed and duplex mis-match, are there any commands that would highlight this on the G450?? I thought the show interface command would have shown input/output errors, CRC, collisions etc. I've checked the GW and it's showing no issues on the interface.
The users have been experiencing call cut-offs, clipping of speech and general poor speech quality - Are these symptoms common with Speed/Duplex mis-matches??
Thanks
