The IDS-4250-XL has a TCP reset interface—INT0. The IDS-4250-XL has a
specific TCP reset interface because it cannot send TCP resets on its monitoring
ports.
If you have reset problems with the IDS-4250-XL, try the following:
Make sure the TCP reset interface of the IDS-4250-XL (int0) is connected to
•
the same switch as the sensing ports (int2 and int3) of the XL card.
• If the sensing ports are access ports (a single VLAN), you must configure the
reset port to be in the same VLAN.
If the two XL ports are access ports for different VLANs, you can
Note
only configure the reset port for one of these VLANs. You can use
dot1q trunk ports to overcome this limitation.
If the sensing ports are dot1q trunk ports (multi-VLAN), the sensing ports and
•
reset port all need to have the same native VLAN, and the reset port needs to
trunk all the VLANs being trunked by both the sensing ports.
