Re: SPAN on 6500 - maximum of 1 TX monitor interface(s)

This issue is due to the hardware limitations of Cisco Catalyst switches. Traffic monitoring in a SPAN session has these restrictions:

1. You can monitor incoming traffic on a series or range of ports and VLANs.

2. You can monitor outgoing traffic on a single port.

3. You cannot monitor outgoing traffic on multiple ports.

4. You cannot monitor outgoing traffic on VLANs.

You need to include a "show ver" with your post, but this is the general guidelines:
