XSR Getting Started Guide 3-23
XSR(config-cmap)#match access-group 133
+ Assigns ACL 133 to this class map
XSR(config)#policy-map priority-policy
+ Adds a policy map and acquires Policy Map mode
XSR(config-pmap)#class rtp_class
+ Adds a queue for this policy map and acquires Class sub-mode
XSR(config-pmap-c)#priority high 30 3200
+ Gives high priority queue a peak 30% of bandwidth and a burst size of 3200 bits per second
XSR(config-pmap-c)#set ip dscp ef
+ Configures IP precedence to match packets with Expedited Forwarding
XSR(config-pmap)#class priority-server
+ Adds another queue for this policy map and enters Class sub-mode
XSR(config-pmap-c)#priority medium 20 6400
+ Gives medium priority queue peak 20% of bandwidth and burst size of 6400 bits per second
XSR(config)#policy-map data_policy
+ Adds a policy map and acquires Policy Map mode
XSR(config-pmap)#class data_class
+ Adds a queue for this policy map and acquires Class sub-mode
XSR(config-pmap-c)#police 24000 2400 4800 conform-action transmit
exceed-action set-dscp-transmit 23 violate-action drop
+ Sets traffic policing at an average rate of 24000 bits per second, a normal burst size of 2400 bits per second, and an excess
burst size of 4800 bits per second. Packets conforming to values are sent, those exceeding are set to a DSCP value of 23
and those violating values are dropped.
XSR(config-pmap-c)#bandwidth percent 50
+ Gives the class a minimum 50% of the bandwidth
Configure WAN/Frame Relay Port
This port’s IP address is 154.68.1.47. The attached switch operates at 128,000 bps, with auto LMI
type, and traffic shaping enabled. Any QoS values set will be applied to the DLCIs: do not apply
QoS to the port, it is not recommended on Frame Relay connections. Note that some commands
are abbreviated.
XSR(config)#interface serial 1/0
+ Configures Frame Relay interface: Serial card in slot 1, port 0 and acquires Interface mode
XSR(config-if)#media-type v35
+ Selects type for Frame Relay
XSR(config-if)#no shutdown
+ Enables the interface
XSR(config-if)#encapsulation frame-relay
+ Enables FR encapsulation
XSR(config-if)#frame-relay class CLASS-FRP
+ Adds a FR map class
XSR(config-if)#frame-relay traffic-shaping
+ Enables map class values
XSR(config)#interface serial 1/0.1 multipoint
+ Adds FR port: serial card in slot 1, port 0, sub-interface 1 for multipoint connections and acquires Interface mode
XSR(config-if)#frame-relay interface-dlci 33
+ Adds PVC #33
XSR(config-if)#no shutdown
+ Enables the DLCI port
XSR(config-if)#ip address 154.68.1.47 255.255.255.0
+ Configures the IP address of the port
