So many TXerror

Hi,

Why would i been receiving error on Txerrors.

Tx coll and Tx Deferred, should they not be the same count if the collision occurs and the packet is deferred?

Port Tx Error Monitor
Port Link Tx Tx Tx Tx Tx Tx
State Coll Late coll Deferred Errors Lost Parity
================================================================================
1 R 0 0 0 0 0 0
2 A 1530 0 2639 0 0 0
3 R 0 0 0 0 0 0

Thanks

It it's twisted pair, first check cables, connector and length.

Than check autoneg,, speed and duplex settings on both ends.

Hi,
Everything is auto neg,

why would you recommend the cable, have you seen this error before?

Thanks

If both sides on autoneg, verify that they choose and run on the same speed and duplex settings.

Late collusions meens the first bytes of the packet were send but then another one also starts sending during the medium is still occupied.
It's typical for 10 Mbit/s with duplex mismatches.

But it also can be caused by a short circuit or something.
