Troubleshooting an operational failure
Traffic is not flowing
•
For tagged unicast or multicast packets, verify the receiving and transmitting interfaces are
configured as either Trunk or Hybrid interfaces and both are members of the VLAN. Use the
show bridge port command.
Troubleshooting VLAN Classification
There are two types of VLAN classification rules that you can create:
•
IPv4 subnet-based VLAN classification rule. If the source IP address matches the IP
subnet specified in the VLAN classification rule, the received packets are mapped to the
specified VLAN: /configure# vlan classification /configure/vlan
classification# rule <id> ip4 {ipaddr/netmask|ipaddr} vlan <vid>
The valid range for the Rule Id is 1-12. The IP address field can be either an IP address,
or a subnet.
• protocol-based VLAN classification rule. If the protocol type matches the protocol
specified in the VLAN classification rule, the received packets are mapped to the specified
VLAN. /configure# vlan classification /configure/vlan
classification# rule <id> protocol <protocol> encap
<encapsulation> The protocol parameter is either a number (between 0-65535) or
ipv4, ipv6, mpls, arp, rarp, vlan-tagged, appletalk, ipx, pppoe-disc, pppoe-session. The
supported encapsulations are Ethernet Type II, LLC SNAP, or LLC Only.
