Chapter 7 Installing the IDSM2

Using the TCP Reset Interface

The IDSM2 has a TCP reset interface—port 1. The IDSM2 has a specific TCP reset interface because it
cannot send TCP resets on its sensing ports.
If you have reset problems with the IDSM2, and the switch is running Catalyst software, try the
following:

If the sensing ports are access ports (a single VLAN), you need to configure the reset port to be in
the same VLAN.
If the sensing ports are dot1q trunk ports (multi-VLAN), the sensing ports and reset port all must
have the same native VLAN, and the reset port must trunk all the VLANs being trunked by both the
sensing ports.
In Cisco IOS when the IDSM2 is in promiscuous mode, the IDSM2 ports are always dot1q
Note
trunk ports (even when monitoring only 1 VLAN), and the TCP reset port is automatically
set to a trunk port and is not configurable.
