I am configuring a Supervisor 2T with the vlan interface
and it is giving me the error "bad mask" (won't accept)
ip classless is enable, and ip subnet-zero is a default yes?
Why isn't it taking that network? isn't it valid? (192.168.94.1 - 63 /26)
If the same subnet is being used on another interface you will get a different message
Are you sure this is not because of a typo? I see there are two dots in "..192"

pleae refer to the below:
network address is: 192.168.94.0
first host is : 192.168.94. 1
last host is : 192.168.94.62
Subnet mask is : 255.255.255.192
your host range is from (1 to 62) the next IP address 192.168.94.63 is broadcast address. by then you cannot assign this ip address to your hosts.
briefly you have assign from (192.168.94.1 to 192.168.94.62).
this is correct, if this is an interface of a router, but if you have a MLS; befor you assign any IP aadress you have to apply CLI (no switchport).

I agree that the error bad mask is not the result of overlapping addresses. It typically caused by attempting to use the subnet address, the broadcast address, subnet zero not enabled, or perhaps some typo in the address.
I would like to see the output of show ip interface for the interface in question. I think that the output of show ip protocol might also be helpful.
