I have 3.1.1 SP3 security manager. I added IPS 28xx routers but I cant add 877 routers to it. It gives the error message below. Do you know the workaround for this?
My 877 router has C870-ADVIPSERVICESK9-M), Version 12.4(22)T
Failed to communicate with the device. Cause: IOSIPS Error getting SequenceRequest : Unbuffered entity enclosing request can not be repeated.
