Enabling Dldp; Setting Dldp Mode; Setting The Interval To Send Advertisement Packets - HPE FlexNetwork HSR6800 series Configuration Manual

Enabling DLDP

To correctly configure DLDP on the device, first enable DLDP globally, and then enable it on each
port.
DLDP takes effect only on Ethernet interfaces (optical 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.
To enable DLDP:
Step
1. Enter system view.
2. Enable DLDP globally.
3. Enter Ethernet interface
view or port group view.
4. Enable DLDP.

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 DLDP can detect
unidirectional links promptly before network performance deteriorates, set the advertisement interval
appropriate for 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 might occur before unidirectional links
are detected and shut down. If the interval is too short, the number of advertisement packets will
increase. Hewlett Packard Enterprise recommends that you use the default interval in most cases.
The Advertisement packet sending interval applies to all DLDP-enabled ports.
