11. Configuration Steps – Policy Configuration

11.1 Role Combination

A role combination is formed by assigning one or more physical ports to the role and by
designating the interface class (Trusted, Untrusted, Un-restricted) for the r ole and associated
ports. By default, when using the WEB interface, all ports on the Ethern et Routing Switch 5500
are assigned to the default interface group named ‘allBayStacklfcs ’ which has an interface class
of untrusted. A port on the Ethernet Routing Switch 5500 can only belon g to one role
combination.
When configuring a policy, an interface group will be assigned to the p olicy.
To add a new role combination, complete the following steps:
a) Add a n ew Interface Group:
• ERS5500-48T(config)#qos if-group name <name> class
<trusted|unrestricted|untrusted>
b) Assign t he physical ports to the Interface Group:
• ERS5500-48T(config)# qos if-assign port <port #> name <if-group name>
Example:
• ERS5500-48T(config)#qos if-group name role_one class untrusted
• ERS5500-48T(config)# qos if-assign port 1/5 name role_one
c) View Role Combination:
To view the Role Combination, enter the following command:
• ERS5500-48T#show qos if-assign
