Labnario Huawei From Scratch
When taking into consideration that default settings are invisible in a configuration file, it is a good information that Huawei’s S3700/S5700 switches have such possibility to display default settings for ethernet interfaces. The ‘display this include-default’ command displays the effective configurations in the current view, including the unchanged default configurations.

This command is supported in V100R006C03 and V200R001 software versions.
Let’s add some configuration to the interface:
[labnario-Ethernet0/0/1]display this # interface Ethernet0/0/1 # return [labnario-Ethernet0/0/1]port link-type access [labnario-Ethernet0/0/1]port default vlan 100 [labnario-Ethernet0/0/1]display this # interface Ethernet0/0/1 port link-type access port default vlan 100 # return
Now use ‘display this include-default‘ command again:
[labnario-Ethernet0/0/1]dis th include-default # interface Ethernet0/0/1 portswitch undo shutdown enable snmp trap updown undo set flow-stat interval undo qinq vlan-translation enable undo mac-address learning disable port priority 0 port link-type access port default vlan 100 qinq protocol 8100 undo loopback-detect enable stp enable undo stp config-digest-snoop undo stp no-agreement-check undo stp root-protection undo stp loop-protection stp transmit-limit 147 stp point-to-point auto stp compliance auto stp instance 0 port priority 128 undo port mux-vlan enable undo mac-vlan enable undo ip-subnet-vlan enable undo rmon-statistics undo smart-link flush receive undo smart-link vll-notify enable undo ntdp enable undo ndp enable bpdu enable undo portal local-server enable undo dot1x enable dot1x max-user 256 dot1x port-control auto dot1x port-method mac undo dot1x reauthenticate undo authentication critical eapol-success authentication max-reauth-req 20 undo mac-authen mac-authen max-user 256 mac-authen reauthenticate undo authentication open undo port-auto-sleep enable undo port-security enable undo qinq vlan-translation miss-drop undo port discard tagged-packet mac-learning priority 0 undo mac-address flapping trigger error-down undo mac-address flapping trigger quit-vlan jumboframe enable 9216 undo set flow-statistics include-interframe trap-threshold input-rate 100 resume-rate 100 trap-threshold output-rate 100 resume-rate 100 log-threshold input-rate 100 resume-rate 100 log-threshold output-rate 100 resume-rate 100 trap-threshold error-statistics 3 interval 10 carrier up-hold-time 2000 carrier down-hold-time 0 undo port link-flap protection enable qos wrr qos queue 0 wrr weight 1 qos queue 1 wrr weight 1 qos queue 2 wrr weight 1 qos queue 3 wrr weight 1 qos queue 4 wrr weight 1 qos queue 5 wrr weight 1 qos queue 6 wrr weight 1 qos queue 7 wrr weight 1 trust 8021p outer undo dei enable qos phb marking enable undo arp anti-attack rate-limit enable undo arp-miss anti-attack rate-limit enable undo arp anti-attack check user-bind enable undo ip source check user-bind enable unicast-suppression 100 multicast-suppression 100 broadcast-suppression 100 storm-control interval 5 port type nni undo nd snooping enable undo nd snooping trusted undo dhcpv6 remote-id insert enable undo dhcpv6 remote-id rebuild enable # return
As you can see, the command shows both manually configured and default settings.
What if you want to come back to the previous settings (default):
- Delete configuration one by one:
[labnario-Ethernet0/0/1]undo port default vlan [labnario-Ethernet0/0/1]undo port link-type
- Perform one-touch configuration clearance on an interface:
[labnario]clear configuration interface Ethernet 0/0/1 Warning: All configurations of the interface will be cleared, and its state will be shutdown. Continue? [Y/N] :y Info: Total execute 2 command(s), 2 successful, 0 failed. [labnario]dis cu int eth 0/0/1 # interface Ethernet0/0/1 shutdown # return
All configuration has been deleted. Note that interface went to ‘shutdown‘ state.
