With the addition of the Catalyst 6000 IDS Module, you can integrate your Cisco IDS directly into your network's infrastructure. This line card sensor can then very effectively monitor your network traffic for intrusive activity by examining traffic directly from the switch's backplane. To enable this line card to receive network traffic for analysis, you must actually configure your Catalyst 6000 family switch to pass traffic to the Catalyst 6000 IDS Module's monitoring port. Your two options for capturing network traffic are:
- Switched Port Analyzer (SPAN) ports
- Virtual LAN (VLAN) access control lists (ACL) or VACLs
Of these two options, VACLs provide you with a much more robust capability to specify the type of traffic that you want to capture for analysis by the Catalyst 6000 IDS Module.
