Excluding IPv4 packets from IPSG filtering

Typically, IPv4SG processes all incoming IPv4 packets and discards the packets that do not match IPSG bindings on an interface. This task excludes IPv4 packets with specific source items from IPSG filtering. You can specify source VLANs for IPSG filtering exemption in the current software version. All IPv4 packets from the specified VLANs are forwarded without being processed by IPSG.

To exclude IPv4 packets with the specified source items from IPSG filtering:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Exclude IPv4 packets with the specified source items from IPSG filtering.	ip verify source exclude vlan start-vlan-id [ to end-vlan-id ]	By default, no excluded source items are configured. You can execute this command multiple times to specify multiple excluded VLANs. The specified excluded VLANs cannot overlap.
