Usage Guidelines

Applicable Scenario

After an Eth-Trunk interface is configured, you can run the display trunkfwdtbl eth-trunk command to view information about the Eth-Trunk forwarding table.

The Eth-Trunk forwarding table shows the forwarding status of the Eth-Trunk interface. The forwarding table is divided into two columns:

MASTER: indicates active member interfaces.
SLAVE: indicates standby member interfaces.
- If no standby interfaces are configured and other Eth-Trunk member interfaces are Up, these member interfaces are used as standby interfaces, shown in the SLAVE column.
- If no standby interfaces are configured and no Eth-Trunk member interfaces are Up, interfaces displayed in SLAVE column are the same as those displayed in MASTER column, that is, interfaces back up themselves.

Prerequisites

An Eth-Trunk interface is correctly configured. The Eth-Trunk interface must be created in advance; otherwise, the system prompts an error when you run the display trunkfwdtbl eth-trunk command.

Precautions

A maximum of 16 physical interfaces can be added to the same Eth-Trunk interface. In this case, the forwarding table contains 16 forwarding entries.

Example

# Display the forwarding table of an Eth-Trunk interface.

<sysname> display trunkfwdtbl eth-trunk 1
 Show the Trunk Forwarding Table
 Eth-Trunk1's forwarding table is:

**Table 1** Description of the **display trunkfwdtbl eth-trunk** command output
Item	Description
Eth-Trunk1	Eth-Trunk interface number.
MASTER	Interface number of the active link.
SLAVE	Interface number of the standby link. Eth-Trunk member interfaces back up each other. If only one member interface exists, the active link is also the standby link.
