Configuring TRILL OAM

Configuring TRILL OAM

Context

After TRILL is configured, unicast trace and ping functions can be used to detect TRILL network connectivity. To check the TRILL unicast forwarding path, use the display trill forwarding-path unicast command.
NOTE:

The input parameter must be consistent with the actual hash factor so that a correct outbound interface can be obtained. If the input hash factor is only the source interface, by default, the device will consider that it processes a Layer 2 packet. If the actual packet is not a Layer 2 packet, the actual Layer 3 hash factors must be input. If the actual Layer 3 hash factor is just the source interface, any one of source IP address, destination IP address, source port, and destination port must be input.

In a stack, to view the TRILL unicast forwarding path or use the TRILL unicast trace function, specify the source interface.

On CE8860EI, CE8850EI and CE6860EI, if you want to use flow-based TRILL unicast trace, specify the source-interface parameter to obtain a correct outbound interface. If the source-interface parameter indicates a TRILL user-side port or TRILL user-side Eth-Trunk member port, you must specify the dst-mac and ce-vlan parameters and ensure that the device's MAC entries include the entries with the specified dst-mac and ce-vlan. Otherwise, the correct traffic forwarding path cannot be obtained.

On CE8860EI, CE8850EI and CE6860EI, if you want to check the TRILL unicast forwarding path using the display trill forwarding-path unicast, pay attention to the following points:
  • If the device is an ingress or egress node, you must specify the dst-mac, ce-vlan, and src-interface parameters and ensure that the device's MAC entries include the entries with the specified dst-mac and ce-vlan. Otherwise, the correct traffic forwarding path cannot be obtained.
  • If the device is a transit node, you must specify the src-interface parameter. Otherwise, the correct traffic forwarding path cannot be obtained.

Procedure

  • Run the following trace trill commands to locate TRILL network faults.

    # Perform TRILL unicast trace.

    trace trill [ -h hop-count-value | -t timeout ] * nickname [ interface interface-type interface-number ]

    # Perform flow-based unicast trace.

    trace trill [ -h hop-count-value | -t timeout ] * nickname [ source-mac mac-address | destination-mac mac-address | source-ip ip-address | destination-ip ip-address | source-port port-number | destination-port port-number | ce-vlan ce-vlan-id | eth-type eth-type | protocol protocol-type | source-interface interface-type interface-number ] *

  • Run the ping trill [ -c count | -h ttl-value | -m time | -t timeout ] * nickname command to locate TRILL network faults.
  • Run the display trill forwarding-path unicast role { ingress dst-nickname dst-nickname | transit dst-nickname dst-nickname | egress out-interface eth-trunk interface-number } { eth-type { ip | l2 | dhcp | arp } | src-mac src-mac-address | dst-mac dst-mac-address | src-ip src-ip-address | dst-ip dst-ip-address | ce-vlan vlan-id | src-interface interface-type interface-number | protocol { protocol | gre | icmp | igmp | ip | ipinip | ospf | tcp [ l4-src-port l4-src-port | l4-dst-port l4-dst-port ]* | udp [ l4-src-port l4-src-port | l4-dst-port l4-dst-port ]* } }* command to check the TRILL unicast forwarding path.
