QOS for Alcatel-lucent switches

How to create and implement QOS for Blocking TCP 137-139, TCP445 and UDP 137-139

(Its help for blocking file sharing for different subnet)


Use the Policy Service Command for this

1. Create a Policy Service for every UDP/TCP Port you want to block.

policy service service_name

[protocol protocol]

[source ip port port[-port]]

[destination ip port port[-port]]

[source tcp port port[-port]]

[destination tcp port port[-port]]

[source udp port port[-port]]

[destination udp port port[-port]]

2. Map these Policy Services to a Policy Service Group

policy service group service_group service_name1 [service_name2...]

3. Map this Policy Service Group to a Policy Condition.

policy condition condition_name [service group service_group]

4. Create a 2 Nos Policy Action One for Accept and other for Deny…

policy action action_name [disposition {accept | drop | deny}]

5. Map the above to a Policy rule……

policy rule rule_name [enable] [precedence precedence] [condition condition] [action action] no validity period]

6. Apply the Policy created……

qos apply
