Monitoring SDP Binding Services

[mandud]

Hi,

Is there any way to monitor traffic utilization from sdp that bind in the services ?
There're many flooding from several sdp, but I can't find out which sdp

In the services there're 100 sdp binding, so I want to know which sdp that make problems

Thanks

You can see the ingress and egress forwarded packet statistics for an sdp with the command

monitor service id sdp {<sdp-id[:vc-id]>|far-end <ip-address>} [interval <seconds>] [repeat <repeat>] [absolute|rate]

But if you have hundreds of them, probably better to graph them.
The SNMP objects are sdpBindBaseStatsIngFwdOctets and sdpBindBaseStatsEgressForwardedOctets

Hi Mivens,

Thanks your advice, actually I've tried this command but the result error

Code: Select all

A:SR-7# monitor service id 1647 sdp 68:1647 interval 
Error: Missing parameter data
A:SR-7# monitor service id 1647 sdp 68:1647 interval 3 repeat 2                                                            ^
Error: Invalid parameter. 
A:SR-7# monitor service id 1647 sdp 68:1647 interval           
  - sdp {<sdp-id[:vc-id]>|far-end <ip-address>} [interval <seconds>] [repeat <repeat>] [absolute|rate]
 <sdp-id[:vc-id]>     : sdp-id - [1..17407]
                        vc-id  - [1..4294967295]
 <ip-address>         : a.b.c.d - display sdp having this as far-end ip-address
 <seconds>            : [11..60] - default 11
 <repeat>             : [1..999] - default 10
 <absolute|rate>      : keywords - default mode delta
A:SR-7# monitor service id 1647 sdp 68:1647 interval 

Based on investigation flooding came from broadcast traffic (broadcast storm) in this services VPLS
is there any way to prevent this in 7750 SR-7 ?

Thanks

The minimum interval is 11:

<seconds>            : [11..60]

so the command would be

monitor service id 1647 sdp 68:1647 interval 11 repeat 2

There are various ways of controlling the flooding of traffic in a VPLS service. There are features such as Auto-Learn MAC Protect and MAC Move that you can configure and that can generate alarms to help you detect and troubleshoot. A service ingress QoS policy can be configured to rate-limit broadcast/unknown MAC traffic etc.
