DAI should build dynamic entries (ACLs) with IP addresses (obtained through DHCP) and corresponding MAC addresses for the phones and PCs.

If a laptop with a statically configured IP address (in the y VLAN) is connected to a switch port associated to the y VLAN, the DAI should prevent the laptop from obtaining network connectivity; that is, it builds a deny ACL for this laptop.

Passed

Set up to verify DHCP snooping and Dynamic ARP inspection on one of the access switches

Figure 1, Private WAN, Cisco Unified CME Mode, or

Figure 2, Private WAN, Cisco Unified SRST Mode, or

Figure 3, MPLS WAN, Cisco Unified CME Mode, or

2. Configure the port security aging timer to be 2 seconds, and configure the port security violation policy to Restrict.

3. Connect a laptop to the switch port.

4. After the laptop gets an IP address through DHCP, disconnect the laptop and connect a different laptop to the same switch port.

2. Connect a traffic generator to the switch port on which the IP source guard is configured, and send line rate traffic to HQ.

3. Obtain the IP address of the traffic generator, using DHCP before sending the traffic.

4. After sending traffic for about 15 minutes, change the source MAC address of the traffic generator connected to the switch port, and observe the behavior.

The traffic from the traffic generator should be successfully allowed from the switch port and should reach the traffic generator at HQ.

The IP source guard feature validates the source MAC address of the host that is connected to the switch port on which the IP source guard is enabled. It associates the host MAC address to the IP address obtained through DHCP.

Once the traffic generator MAC address is changed, traffic should be dropped and not be allowed to pass from the switch port.

Passed

7. Configure policing (rate limiting) for each class.

8. Configure Catalyst switch egress queue in 1P3Q3T mode, that is, set up Q1 as the priority queue to carry all voice traffic, and set up the rest of the three queues in shared-bandwidth mode. Assign Q2 for mission-critical data traffic, Q3 for best-effort traffic, and Q2 for scavenger and bulk traffic. Configure shared weights of 70, 25, and 5 for Q2, Q3, and Q4, respectively.

9. Configure Weighted Tail Drop (WTD) thresholds per queue as shown in Figure 33. For Q2 set the first threshold to 70% and the second threshold to 80%. For Q4, set the first threshold to 40% and the second threshold to 100%.

show mls qos

show mls qos map

show mls qos interface

show mls qos interface policers

show class-map

show policy-map

show policy interface

Voice and data packets should be properly marked by the switches.

Excess traffic should be re-marked to scavenger class and dropped if the scavenger class limit is also exceeded.

Queuing should be engaged only during congestion.

Each traffic type should be properly queued based on the queue assignments.

Passed

Enable 8-class hierarchical QoS on the primary WAN interface

1. Configure class maps for voice, voice signaling, interactive video, mission-critical data, transactional data, internetwork control, bulk/scavenger data, and best-effort data.

4. Match interactive video-based on a DSCP value of 34, and also based on IP address/port number using ACLs. Use port number range 16384 to 32768.

5. Match mission-critical data traffic-based on a DSCP value of 25, and also based on IP address/port number using ACLs.

6. Match transactional data traffic, based on a DSCP value of 18, and also based on IP address/port number using ACLs.

7. Match internetwork control traffic, based on a DSCP value of 48, and also based on IP address/port number using ACLs.

8. Match bulk/scavenger traffic, based on a DSCP value of 8, and also based on IP address/port number using ACLs.
