announced it will
implement the inter-switch link (ISL) protocol from Cisco Systems
in its HP Internet
Advisor network testing tool. Using the ISL protocol, an administrator
can gather and decode statistics on virtual LAN (local area network)
traffic, such as the percentage of network traffic a VLAN implementation
is taking up. A VLAN is a broadcast domain on a network of switches that
is intended for users in different sites.
The VLAN test capability is available now from HP.
