Crypto map removing itself after reload

[Jwillmanaesd]

Hello,

I just set up my site tot site vpn with a pix box and a cisco 3745.

The pix box is fine but the 3745 when ever I reload it the crypto map is not applied to the interface after the reload.

hi john,

just to cover basics, did you save the config by doing a write memory?

also, what's the show version output? it could be a confreg issue.

hi,

i highly suspect this could be an IOS bug on your 3745.

try updating the IOS and test again.

loosing part of config (in crypto-maps) after reload or power-cycle

CSCeb20989

Description

Symptoms: After a Cisco router has reloaded, part of the configuration that is
defined in the startup configuration may not show up in crypto maps.
Conditions: This symptom is observed on any Cisco platform that has an
interface that requires a controller statement under the following conditions:
- You enter the crypto map map-name
local-address interface-id global
configuration command.
- For the interface-id argument, you enter the interface
that is configured by the controller statement.
- There are more than 35 instances of the crypto map
map-name local-address
interface-id global configuration command in the startup
configuration.
Workaround: After the router has reloaded, enter the copy
startup-config running-config EXEC command.

Thanks I never considered it to be a bug but the update did fix the problem.
