Enabling Dldp; Setting Dldp Mode; Setting The Interval To Send Advertisement Packets - HP 6125G Configuration Manual

Enabling DLDP

To properly configure DLDP on the device, first enable DLDP globally, and then enable it on each port.
To enable DLDP:
Step
1. Enter system view.
2. Enable DLDP globally.
3. Enter Layer 2 Ethernet
interface view.
4. Enable DLDP.
NOTE:
DLDP takes effect only on Ethernet interfaces (fiber or copper).
•
DLDP can detect unidirectional links only after all physical links are connected. Therefore, before
•
enabling DLDP, make sure that optical fibers or copper twisted pairs are connected.

Setting DLDP mode

DLDP operates in normal or enhanced mode.
In normal mode, DLDP does not actively detect neighbors when the corresponding neighbor entries age
out.
In enhanced mode, DLDP actively detects neighbors when the corresponding neighbor entries age out.
To set DLDP mode:
Step
1. Enter system view.
2. Set DLDP mode.

Setting the interval to send advertisement packets

DLDP detects unidirectional links by sending Advertisement packets. To make sure that DLDP can detect
unidirectional links promptly without affecting network performance, set the advertisement interval
appropriately depending on your network environment. The interval should be set shorter than one third
of the STP convergence time. If the interval is too long, STP loops may occur before unidirectional links
are detected and shut down. If the interval is too short, the number of advertisement packets will increase.
HP recommends that you use the default interval in most cases.
To set the interval to send Advertisement packets:
Step
1. Enter system view.
