Summary

0000921: generateFakeMac() in Cisco.pm does not work on Catalyst 2960 with Fa and Gi nor with Staked switches

Description

In the actual generateFakeMac() function we use the 2 last numbers of the ifIndex to generate a fake MAC to secure on a port.There canot be the same MAC address secured on 2 different ports at the same time.

Issue 0000001:
On a Catalyst 2960, ifIndex start from 10001 to 10047,48 for FastEthernet and from 10101 for GigEthernet. So we canot secure Fa0/1 and Gi0/1 cause the fake MAC generated for each of them is 0200.0000.0001

Issue 0000002
On a stacked Catalyst 3750:
- IfIndex starts at 10101 on module 1
- IfIndex starts at 10601 on module 2
- IfIndex starts at 11101 on module 3
- IfIndex starts at 11601 on module 4
...
Here again if we secure Fa0/1 on each module, the fake make generated is 0200.0000.0001.
