Can anyone give me an approximate SWAG as to when IOS 11.0 and 11.2 code was released?
According to this link:
Cisco IOS 11.0 is a direct superset of Cisco IOS 10.3(x) and was released on September 18, 1995. Cisco IOS Software 11.0 reached the GD milestone on September 23, 1996 at maintenance revision 11.0(11). All subsequent maintenance releases thereafter are also GD certified.
And according to this link:
Cisco IOS 11.2 was deployed in October, 1996, as the first major release of the next generation of release process. 11.2P and 11.2F immediately followed it.
