Question:
on the cisco7204vxr router how can i find out what is the current speed of an interface is negotiated to?
"show int status" command is not available on this router,


..from the "show int gi0/1"... i see the following..
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,


does this mean the speed in negotiated to 1GB?

...
from the config file
...

!
interface GigabitEthernet0/1
description somenet
ip address xxx.xxx.xxx.xxx 255.255.255.248
ip access-group 100 in
no ip proxy-arp
ip route-cache flow
load-interval 30
duplex auto
speed auto
media-type rj45
negotiation auto
!
....

 
I can't think of a way within the IOS to view what speed/duplexing the autonegotiation has actually agreed upon; I suppose you could just look at the link-light if you have physical access to the router, else you could hard-set the interface to gigabit/full rather than let it autonegotiate.
 
thx gents..
this device is located on remote location, i don't have physical access to it..
but likeS teveTheGeek suggests i will have somebody to take a look at a link light.
 
The below command will help.It from a 1GB interface connected to 100MB switch.It's also configured for auto speed and duplex.

Router#show int gigabitEthernet 0/0
GigabitEthernet0/0 is up, line protocol is up
Hardware is MV96340 Ethernet, address is 001a.6df3.08b8 (bia 001a.6df3.08b8)

MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 100Mb/s, media type is T
output flow-control is XON, input flow-control is XON
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:00:50, output 00:00:05, output hang never

Minue,
You da man! the output of yours sh int confirmed that if the speed is negotiated to 100000 it will be shown in

BW 100000Kb

and... it looks like... there also will be " Full-duplex, 100Mb/s ": displayed

Thank you,
