Page 20: Configuring Dampening On An Ethernet Interface
Configuration restrictions and guidelines Do not enable this feature on an interface with RRPP, spanning tree protocols, or Smart Link enabled. This command, the dampening command, and the port link-flap protect enable command are mutually exclusive on an interface. You can configure different suppression intervals for link-up and link-down events. If you execute the link-delay command multiple times on an interface, the following rules apply: •... - Page 21 When configuring the dampening command, follow these rules to set the values mentioned above: • (Max-suppress-time/Decay) The ceiling is equal to 2 × reuse-limit. It is not user configurable. • The configured suppress limit is lower than or equal to the ceiling. •...

Page 22: Enabling Link Flapping Protection On An Interface
Enabling link flapping protection on an interface Link flapping on an interface changes network topology and increases the system overhead. For example, in an active/standby link scenario, when interface status on the active link changes between UP and DOWN, traffic switches between active and standby links. To solve this problem, configure this feature on the interface. -
Page 23: Configuring Link Compensation
When the FEC mode is set to auto on an interface, the actual FEC mode of the interface depends on the model of the transceiver module installed. To view the actual FEC mode, see the FEC mode field in the display interface command output. Make sure you set the same FEC mode for both interfaces of a link. -
Page 24: Configuring Generic Flow Control On An Ethernet Interface
• External loopback testing—Tests the inter-device link. The Ethernet interface sends incoming packets back to the remote device. If the remote device fails to receive the packets, the inter-device link fails. Configuration restrictions and guidelines • After you enable this feature on an Ethernet interface, the interface does not forward data traffic. -
