Configure NAT on AR router interface can be configured multicast, but the configuration of the NAT only effect on unicast packets, multicast packets are not supported in NAT.
You can enable the packet capture function on the USG2000&5000 as follows:
1. Configure the packet capture queue.
[USG] packet-capture all-packet queue 0 interface GigabitEthernet 0/0/1
2. Enable the packet capture function.
[USG] packet-capture startup manual
3. Save packets in the specified queue as file 1.cap on the device. The default directory is hda1:/.
[USG] packet-capture queue 0 to-file 1.cap
4. Use FTP to download file 1.cap from the device, use the packet capture software to open the file, and analyze the captured packets.
5. Clear the packet capture queue and release the memory.
After confirming that the host has completed receiving the packets, delete all packets from the queue.
reset packet-capture queue 0
You can enable the packet capture function on the USG6000 as follows:
1. Enable the packet capture function through the CLI as follows:
a. Define the packet capture range. In this example, packets from 192.168.1.0 are captured.
system-view
Enter system view, return user view with Ctrl+Z.
[sysname] acl 3000
[sysname-acl-adv-3000] rule permit ip source 192.168.1.0 0.0.0.255
[sysname-acl-adv-3000] quit
b. Run the following command to put all IPv4 packets passing the interface and matching ACL 3000 to the packet sending queue.
[sysname] packet-capture ipv4-packet 3000 interface GigabitEthernet 1/0/1
c. Start to capture packets.
[sysname] packet-capture startup manual
d. Save packets in the specified queue as file 1.cap on the device. The default directory is hda1:/.
[sysname] packet-capture queue 0 to-file 1.cap
e. After packet capture completes, terminate the packet capture process.
[sysname] undo packet-capture startup
f. Use FTP to download file 1.cap from the device, use the Wireshark to open the file, and analyze the captured packets.
