I have a problem of duplex negociation in my switch. I have two 3560 switchs connected via Gi0/0 port using fibr. when i launch in the second SW the sh mac-address-table i see two mac-addresses connected to my fa0/9 :
mac1 (HSRP) fa0/9
mac2 (device) fa0/9
SW2#sh spaningtree root
I get fa0/9
SW#sh int fa0/9
i get hal-duplex and 100MB/s
i get fa0/9 connected using Shr Type
Is someone have an idee why i get the HSRP + 2 mac for the same port ? why is in half-duplex ?
if the type of cable used to connect a device to fa0/9 is crossover, thus the duplex is automaticaly half ?
is there any possibility to have a Hub behind fa0/9 ? how can i detect that ?
Special question : i have been connected using telnet to my two switch with ter mon option, and when the fa0/9 of the second switch has been disconnected , i get the message that the interface gone down in both screens ? what does means ? it's normal ? i think the message would be displayed only in the second SW.
in the port Fa0/9: it's connected a 3G cisco router and all port configurations in the router are to auto. Acoording to a local technician, the problem of duplex may be caused by crossover cable, used to connect the router to switch.
if the cable is crossover, it's normal to have halp-duplex ?
SW and SW 2 are connected via fibr (Gi0/1).
for Special question:
SWs are connected via Gi0/1 port. it's normal to see information and alerts in both screen when there is a change only in one SW (i.e : fa0/9 of SW2)?
Please help me to understand connection between cisco /hub and crossover cables.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
