Displaying the Output Policy Interface Configuration
To display the policy map configuration on the enhanced ATM router module interface, use the following
privileged EXEC command:
Example
In the following example, the show epc ipqos output interface command displays the configuration of
the policy-map arm2-switch1 on the enhanced ATM router module:
Switch1# show epc ipqos output interface atm 9/0/0
Policy Assigned : TRUE Initialized : TRUE
Broute VCs Created : TRUE CoS Enabled : TRUE
IPQOS HW interface Num: 8 Number of Assigned Classes: 4
MMC Port: 68 MSC ID: 4 Port num in MSC:0
Policy Name : arm2-switch1
Queue Class Class Sched Wei/Pri Buff Copied Default EPD EFCI Drop
ID Name From Def. Traffic Policy

1 2 hipri WRR 25 1 FALSE FALSE TRUE TRUE XRED

3 0 voice WRR 51 3 FALSE FALSE TRUE TRUE XRED

Mapping the IP to ATM Configuration
In our example topology, shown in Figure 25-11, the ATM tunnel interface ATM 0/0/0.11 is connected
to the Catalyst 8540 MSR at Switch 2. This requires the PVCs and bundled PVCs terminating on the
enhanced ATM router module subinterfaces to transit the correct ATM tunnel port depending on the
destination.
Creating the Traffic Rows for PVCs and VC-bundle Members
The link from Switch 1 to Switch 2 is 10 Mbps. Hence we need one CTTR row of type CBR for creating
the hierarchical tunnel, and the others for CBR/VBR VCs transiting this tunnel.
For information about creating hierarchical tunnels see the, “Configuring a Hierarchical VP Tunnel for
Multiple Service Categories” section.
The following commands configure the connection traffic table rows needed for the ATM connection
between Switch 1 and Switch 2:
Switch1(config)# atm connection-traffic-table-row index 500 cbr pcr 10000
Switch1(config)# atm connection-traffic-table-row index 501 cbr pcr 10000
Switch1(config)# atm connection-traffic-table-row index 301 vbr-nrt pcr 2000 scr0 1640
Switch1(config)# atm connection-traffic-table-row index 302 vbr-nrt pcr 1500 scr0 1200
Switch1(config)# atm connection-traffic-table-row index 303 vbr-nrt pcr 400 scr0 350
Switch1(config)#
