Configuring Cfd Functions; Configuration Prerequisites; Configuring Cc On Meps - HP 5900 Series Configuration Manual

Changes occur to the VLAN attribute of a port.
•
• The rule specified in the cfd mip-rule command changes.
An MA with no VLAN attribute is mainly used to detect direct link status. It cannot generate MIPs.
For an MA with VLAN attribute, if the same or higher level MEP exists on the interface, no MIP is
generated for the MA on the interface.
To configure the rules for generating MIPs:
Step
1. Enter system view.
2. Configure MIP
auto-generation rules.

Configuring CFD functions

Configuration prerequisites

Complete basic CFD settings.

Configuring CC on MEPs

Configure CC before configuring other CFD functions. After the CC function is configured, MEPs in an
MA can periodically send CCM frames to maintain connectivity. When the lifetime of a CCM frame
expires, the link to the sending MEP is considered disconnected. When setting the CCM interval, use the
settings described in
Table 5 CCM interval field encoding

Follow these guidelines when you configure CC on a MEP:
Configure the same CCM interval field value for all MEPs in the same MA.
•
The switch does not support a CCM interval field value in the range of 1 to 3. If you configure a
•
CCM interval field value of 1, 2, or 3, the value of 4 takes effect.
Configurations in Ethernet interface view take effect only on the current interface.

Remarks
N/A
By default, no rules for generating
MIPs are configured, and the
system does not automatically
create any MIP.
