• The LAN port of SecPath is connected to the hosts, and the uplink port GigabitEthernet 0/1 is
connected to the Internet.
• Subinterface 1 of GigabitEthernet 0/1 obtains its IP address through DHCP.
Configure SecPath to forward SNMP packets and SNMP traps through subinterface 1 of GigabitEthernet
0/1.

Configuration procedure
# Configure subinterface 1 of GigabitEthernet 0/1 (GigabitEthernet 0/1.1) to obtain its IP
address through DHCP.
<SecPath> system-view
[SecPath] interface GigabitEthernet 0/1.1
[SecPath-GigabitEthernet0/1.1] ip address dhcp-alloc
[SecPath-GigabitEthernet0/1.1] vlan-type dot1q vid 1
[SecPath-GigabitEthernet0/1.1] quit
# Define ACL 3000 to match management packets (SNMP packets and SNMP traps).
[SecPath] acl number 3000

[SecPath-acl-adv-3000] rule 5 permit udp destination-port eq snmptrap
[SecPath-acl-adv-3000] quit
# Define Node 1 of policy management, so that management packets are forwarded via
GigabitEthernet 0/1.1. (Because GigabitEthernet 0/1.1 obtains its IP address through DHCP and
thus the next hop address is unknown, you need to specify the gateway address learned through
DHCP as the next hop address.)
