Indication of the minimum side mode suppression ratio


It is a parameter of a single longitudinal mode (SLM) laser. It indicates the minimum ratio of the average optical power of the main longitudinal side mode to the optical power of the most prominent side mode. If the parameter value is too small, large dispersion may be generated after long-distance transmission.

Traffic suppression modes for S series switches
Traffic suppression can be configured on interfaces of S series switches. Traffic suppression has the following modes: By number of packets per second (pps) By number of bits per second (bit/s) By bandwidth percentage Note: Only some S series fixed switch models support traffic suppression by number of bits per second (bit/s).

Board-side status after alarm suppression is enabled on an OSN 6800 NE
Question: There is no other alarm except R_LOS on an NS2 board on an OSN 6800 NE. Does the running status indicator of the board turn red or green if the R_LOS alarm is suppressed on the NMS? Does the indicator on the system control board turn red or green? Does the indicator on the top of the cabinet turn red or green? Analysis: None Root cause: None Answer: Generally, an NE on which alarm suppression is enabled does not monitor related alarms. The suppressed alarms are not reported on either the U2000 or NE. The indicator status, however, varies according to NE types. The OSN 6800 uses the alm-set-monevent command to configure alarm suppression on a board, and the indicator on the board and the indicator on the system control board turn green after alarm suppression is enabled. The indicator on the top of the cabinet reflects alarms of the system control board and therefore is green. Suggestion and conclusion: When alarm suppression is enabled on a board on an NG SDH NE and the NE actually still has alarms, the SRV indicator on the board is red. When alarm suppression is enabled on a board on a Metro 2500+ NE and the board has an alarm, the indicator is green.

Example for Configuring Multicast Packet Suppression in Tunnel Forwarding Mode
In V200R005, the configuration procedure is as follows:
Create the traffic classifier test and define a matching rule.
[AC6605]traffic classifier test
[AC6605-classifier-test]if-match destination-mac 0100-5e00-0000 mac-address-mask ffff-ff00-0000 //Match the destination MAC address of multicast packets.
Create the traffic behavior test, enable traffic statistics collection, and set the traffic rate limit.
[AC6605]traffic behavior test
[AC6605-behavior-test]statistic enable
[AC6605-behavior-test]car cir 100 //Set the rate limit to 100 kbit/s. If multicast services are available, you are advised to set the rate limit according to the service traffic.
Create the traffic policy test and bind the traffic classifier and traffic behavior to the traffic policy.
[AC6605]traffic policy test
[AC6605-trafficpolicy-test]classifier test behavior test
Apply the traffic policy to inbound or outbound directions of interfaces.
[AC6605]interface wlan-ess 1
[AC6605-Wlan-Ess1]traffic-policy test inbound
[AC6605-Wlan-Ess1]traffic-policy test outbound
In V200R006 and later versions, the configuration procedure is as follows:
Create the traffic profile test and set the maximum traffic volume of multicast packets in the profile.
[AC6605-wlan-view]traffic-profile name test
[AC6605-wlan-traffic-prof-test]traffic-optimize multicast-suppression packets 100//Set the maximum traffic volume of multicast packets to 100 pps. If multicast services are available, you are advised to set the rate limit according to the service traffic.
Bind the traffic profile to the VAP profile.
[AC6605-wlan-view]vap-profile name test
[AC6605-wlan-vap-prof-test]traffic-profile test
