Copy Start TFTP Issue

[nigel doe]

Hi all,

Bit of a strange problem reared its head today.

Trying to copy the startup config to a remote tftp server is not working when copying from my 3750G switch, all other switch config transfers are ok.

ACL has been configured on an inbound routed interface that joins this and another L3 switch together.

permit ip any any (obviously works), changing this to:

permit udp any any eq tftp log carries on working for my other switches but the 3750G gets one ! then times out completely. I'm not sure why this is not working?

Any suggestions are welcome.

Thanks.

Pete,

If your switch has multple IP address (L3 ints & SVIs)

Select the interface that should be able to route to the tftp server and use this int to source the tftp packets on the switch

add this to your global config

!

ip tftp source-interface vlan 555

!

(Use the interface that can communicate with the tftp server- I have shown vlan 555 just as an example)

Regards,
Alex.
