Cat5k port problem


Picture this; I have two CAT5k switches connected with fibre, the rest of the blades are std 48 port eth. I am working at a terminal directly connected to switch 2. I can ping switch 1 but not switch 2. I telnet to the switch at the other end of the fibre (switch 1) and from the console of 1 I can telnet back to switch 2. Once telnetted via 1 into switch 2 I can show all the ports and everything seems fine, so why doesn't 2 return my ping? Any hints gratefully appreciated...

Re: Cat5k port problem



1) What is the native VLAN of each switch?

2) Is the fibre trunking?

3) Is the "directly connected terminal" a telnet session from a PC or are you consoled into switch 2?

4) What are the IPs involved?

5) Is there a router involved?

6) If you're not consoled in, what is the IP and default gateway on the PC?

7) Is there a default gateway on the switches?

Re: Cat5k port problem

Hi Mick,

1) What do mean native VLAN?

2) The fibre ports connect the two switches together and are not trunk ports

3) The directly connected terminal is via telnet to switch 2

4) the IP's of the switches are and

5) theres no router between the switches as they live on the same subnet but I am on a different subnet = 172.16.x.x

6) the PC is on and its default gateway is

7) Yes, but I don't know what it is until a week monday (i'm on a course)

Sorry the informations sketchy...
