dhl num mac-flushing

Configures the MAC-flushing technique for the DHL session. The MAC-flushing technique is used to

correct any stale MAC entries that are caused when a dual homed link goes down.

dhl num dhl_num mac-flushing {none | raw | mvrp}

Syntax Definitions

none | raw | mvrp

Platforms Supported

OmniSwitch 6400, 6850, 6850E, 6855, 9000E

Usage Guidelines

Before enabling MVRP on dual homed links, the Registrar Mode should be set to 'forbidden', failing

which an error message is displayed when configuring DHL. If the Registrar Mode is set to 'not forbid-

den, then changes cannot be made to the MVRP configuration on the dual homed links.

If the mac-flushing technique is set to MVRP and if MVRP is not enabled on the dual homed links,

enabled on the dual homed links, then the mac-flushing technique changes to MVRP and the Registrar

Mode of the links is automatically set to 'forbidden'.

If VLANs are moved across the dual homed links as a result of configuration changes, then mac-flush-

ing is automatically enabled, if configured, excepting dual homed links that are changed on the fly..
