Recommended Configuration For UDLD Aggressive Mode

I have point-to-point links in my LAN between Distribution and Access layer switches and want to enable UniDirectional Link Detection (UDLD) aggressive mode.

Do I need to enable it on both ends or just one? If just one, should it be the Distribution or Access layer switch?

Re: Recommended Configuration For UDLD Aggressive Mode

UDLD aggressive mode will only

work if enabled on both sides of

the connection. UDLD aggressive

mode is a highly-recommended

feature as it prevents Spanning Tree

Protocol (STP) problems and other

failures. All connections between

switches should have this feature

enabled.
