Optional) Setting Arp Detection Parameters; Optional) Setting The Type Of A Nas Interface - Huawei S9300 Configuration Manual

S9300&S9300E Terabit Routing Switch
Configuration Guide - IP Service
The service policy associated with the service scheme for users going online is configured.
By default, users connected to a sub-interface go online through the service scheme in the domain
bound to the sub-interface.
After the dhcp service-policy option60 command is used, the S9300&S9300E selects the
related service policy according to the Option 60 field in DHCP messages.

4.3.6 (Optional) Setting ARP Detection Parameters

ARP detection is configured on sub-interfaces. If the ARP detection interval is 0, it indicates
that ARP detection is disabled.
Context
By using the DHCP protocol, a server leases IP addresses to clients. The clients then need to
apply for new IP addresses when the leases expire. In actual applications, the situation that a
client that already has a leased IP address is abnormally disconnected but no release packet is
sent to the DHCP server is often encountered.
In this case, the S9300&S9300E needs to regularly send ARP detection packets to check whether
users remain online. Upon the timeout of the ARP detection, users are disconnected. In addition,
DHCP Release packets are constructed and sent to the DHCP server to enable the DHCP server
to release the IP address.
Procedure
Step 1 Run:
system-view

Step 2 Run:
interface interface-type interface-number.subinterface-number
The sub-interface view is displayed.
Step 3 Run:
dhcp user-detect retransmit times interval interval
The interval and number of detection times are set.
By default, the detection interval is 30 seconds and the number of detection timeout times is 5.
