Cisco SOHO 91 Router showing Ethernet 0 instead of Fast Ethernet 0
Posted by andyr on March 25th, 2005


This is weird. I haven't used a Cisco product with an integrated switch, so
maybe I'm just missing something easy, but shouldn't my internal Ethernet
connection show as a Fast Ethernet connection?

All the documentation I've found on this product shows that it has an
integrated 10/100 switch. It's even lists the 4 LAN ports as 10/100 on the
back of the unit, but when I show interface it shows the following:

Ethernet0 is up, line protocol is up
Hardware is PQUICC Ethernet, address is 0011.20df.8b47 (bia
0011.20df.8b47)
Description: Inside Lan
Internet address is 10.10.10.1/24
MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 10Mb/s
ARP type: ARPA, ARP Timeout 04:00:00

0 output errors, 0 collisions, 0 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out

There doesn't appear to be any speed command available for the interface
either.
I'm using IOS Version 12.3(2)XC2, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1)

Any help would be greatly appreciated.

The docs say that it has Ethernet ports, but a 4 port 10/100 switch.

I'd read that as 10 Mbit Ethernet ports out both sides, but if you
wanted to plug in 100Mbps devices into the switch, its not going to
degrade them from talking to one another down to the port speed it has.

It shouldn't, but when I let the devices Auto Negotiate speed, they
choose 100Mb and the router won't talk to them at 100Mb, only 10Mb.

That means I have to manually set the speed on the devices. This is ok
for most computers, but I have a DVR that doesn't allow me to change
the port speed.

I suppose I could put a 10Mb hub/switch in between the router's built
in switch and the DVR, but thats kinda a rig. I'd think that Cisco
would have a speed option in the IOS somewhere...

Any other ideas?

If this is a SOHO91 it should have 2 ethernet modules not a 4 port
switch. Do a show hard and it will tell you at the bottom what kind of
interfaces you have

IE
ISCO SOHO91 (MPC857DSL) processor (revision 0x301) with 29492K/3276K
bytes of memory.
Processor board ID FOC08520YKK (4255911535), with hardware revision
0000
CPU rev number 7
Bridging software.
2 Ethernet/IEEE 802.3 interface(s) <----- Right there
128K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read/Write)
2048K bytes of processor board Web flash (Read/Write)

I've got one of these SOHO91 ethernet routers and my interfaces show up as
ethernet not fast ethernet, the built in switch on mine (which is eth0 if I
remember correctly) runs at 10mb not 100. I've never bothered with the
switch and run it directly into another 100meg switch for the lan.
