hi,
I installed a switch in my lab

Code: Select all

and i keep getting a duplex miss match:

Code: Select all

*May 24 14:21:48.252: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet0/1 (not full duplex), with BW-SW-01 GigabitEthernet1/0/27 (full
 duplex).

*May 24 14:22:48.396: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet0/1 (not full duplex), with BW-SW-01 GigabitEthernet1/0/27 (full
 duplex).
Switch#

i dont understand why this is happening.
The port is a trunk with multiple VLANs going out of eve-ng to a physical network to a Cisco switch. All is good on the physical cisco switch port is set to auto.

i have refrain from using the dynamips and iol images and have moved on to using vIOS. At least i get Gigabit interfaces, not sure if there are full rate or not but not getting that duplex error anymore.

get images listed in our how to https://www.eve-ng.net/index.php/docume ... -on-linux/
and it should work
