IOS Upgrade

Hi Guys

I?m having a little problem with upgrading a 2600 IOS. When I backup the flash to my TFTP server it takes a few seconds but I try to upgrade the IOS it takes forever but it does complete.

The router and the TFTP server are attached on the same piece of network.

Thanks for looking.

Re: IOS Upgrade

what is the response time you are getting when you ping router IP from TFTP server and vice-versa. check for any packet drops. if there are any packet drops then you need to check all the interfaces which a packet traverse to reach router from TFTP.

Ping from router to TFTP

Altis#ping ip

Target IP address: 172.19.128.225

Repeat count [5]:

Datagram size [100]:

Timeout in seconds [2]:

Extended commands [n]:

Sweep range of sizes [n]:

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 172.19.128.225, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

No problem there then.

Re: IOS Upgrade

Check for errors on the router interface (presumably ethernet?). May be mismatched speed and/or duplex settings (more likely the latter, me thinks).
