Advanced Virtual Wire Health Check Configuration
The Advanced Virtual Wire health check verifies connectivity between the ingress and egress interfaces of a virtual wire device in an SSL inspection deployment. In contrast to the out-of-the-box virtual wire health check (used by the on-device outbound SL inspection wizard), the Advanced Virtual Wire health check can be manually configured, does not require static ARP, and runs on the TCP port defined for the filter rport or the health check destination port. As such, the Advanced Virtual Wire health check works together with either static trunk or LACP trunk.
Note: Alteon supports the Advanced Virtual Wire health check only for IPv4 interfaces.
The following menu example is application-specific and includes only the application-specific commands. For all common commands, refer to cfg/slb/advhc/health <general> General Health Check Configuration.

Command Syntax and Usage
