<sequence-number>

Syntax

<sequence-number> {permit | deny}
 {service-name <SERVICE-NAME> | service-instance-name <SERVICE-INSTANCE-NAME>}
no <sequence-number> {permit | deny}
 {service-name <SERVICE-NAME> | service-instance-name <SERVICE-INSTANCE-NAME>}

Description

Adds a filter rule to the service profile. The sequence number configured determines the priority with which the rule is matched. Lower the sequence number, higher is the priority.

Following are the filter match parameters:

  • Service-name: mDNS packets are matched against the service IDs configured under the service name.

  • Service-instance-name: mDNS packets are matched against the service instance name present in the mDNS packets.

When no match criteria is specified in the rule, then the rule can be matched against any mDNS packet. Once the match is found then either the packet can be permitted or denied based on the action specified in the rule.

The no form of this command deletes the filter configured in the service profile.

NOTE:

When an mDNS packet does not match any of the filters configured in the profile, then the packet is denied.
