VLAN MAC Addresses
The switch has one unique MAC address for each of its VLAN interfaces. You
can send an 802.2 test packet to this MAC address to verify connectivity to the
switch. Likewise, you can assign an IP address to the VLAN interface, and
when you Ping that address, ARP will res olve the IP address to this MAC
address. The switch allows up to 30 VLAN MAC addresses (one per possible
VLAN).
Port Trunks
When assigning a port trunk to a VLAN, all ports in the trunk are automatically
assigned to the same VLAN. You cannot split trunk members across multiple
VLANs. Also, a port trunk is tagged, untagged, or excluded from a VLAN i n the
same way as for individual, untrunked ports.
Port Monitoring
If you designate a port on the switch for network monitoring, this port will
appear in the Port VLAN Assignment screen and can be configured as a
member of any VLAN. For information on how broadcast, multicast, and
unicast packets are tagged inside and ou tside of the VLAN to which the
monitor port is assigned, see 18-11.
