Use undo port hybrid vlan to remove the hybrid ports from the specified VLANs. Syntax port hybrid vlan vlan-list { tagged | untagged } undo port hybrid vlan vlan-list Default A hybrid port only allows packets from VLAN 1 to pass through untagged.
Views Ethernet interface view Default command level 2: System level Parameters access: Configures the link type of a port as access. hybrid: Configures the link type of a port as hybrid. trunk: Configures the link type of a port as trunk. Usage guidelines To change the link type of a port from trunk to hybrid or vice versa, you must first set the link type to access. Examples # Configure GigabitEthernet 0/1 as a trunk port.
The port trunk permit vlan all command can be ineffective to isolate-user-VLANs, but does not display any configuration error message. On a trunk port, only traffic of the PVID can pass through untagged. To prevent unauthorized VLAN users from accessing restricted resources, use the port trunk permit vlan all command with caution. Examples # Assign the trunk port GigabitEthernet 0/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100.

Views System view Default command level 2: System level Parameters isolate-user-vlan-id: Specifies an isolate-user-VLAN ID, ranging from 1 to 4094. secondary secondary-vlan-id [ to secondary-vlan-id ]: Specifies a secondary VLAN ID or a secondary VLAN ID range.
Views VLAN view Default command level 2: System level Usage guidelines An isolate-user-VLAN may include multiple ports, including the one connected to the upstream device. Examples # Configure VLAN 5 as an isolate-user-VLAN.
If the port is a hybrid port, the system automatically assigns the port to the isolate-user-VLAN and its associated secondary VLANs (if the isolate-user-VLAN has been associated with secondary VLANs) as an untagged member (if the port has been assigned to a secondary VLAN as a tagged member, the tagged member attribute is not changed), and keeps the PVID of the port.
# Assign access port GigabitEthernet 0/1 to VLAN 10, which is not an isolate-user-VLAN, configure the port to operate in promiscuous mode in VLAN 10, and then cancel the configuration.
• If the port is an access port and has been assigned to a secondary VLAN, the device changes the link type of the port to hybrid and sets the secondary VLAN as the PVID of the port. • If the port is a trunk or hybrid port and has been assigned to a secondary VLAN, the device does not change the link type or PVID of the port.

Views System view Default command level 2: System level Parameters process-id: Specifies an OSPF process by its ID in the range of 1 to 65535. router-id router-id: Specifies an OSPF router ID in dotted decimal format. vpn-instance vpn-instance-name: Specifies a VPN by its name, a case-sensitive string of 1 to 31 characters. If no VPN is specified, the OSPF process runs on the public network. Usage guidelines You can enable multiple OSPF processes on a router and specify different Router IDs for them.
simple: Enables simple authentication. key-id: Specifies a key ID in the range of 1 to 255. cipher: Specifies a ciphertext password. plain: Specifies a plaintext password. password: Specifies a password. In simple authentication mode, a plaintext password is a case-sensitive string of 1 to 8 characters, and a ciphertext password is a case-sensitive string of 1 to 41 characters.
Use undo ospf cost to restore the default. Syntax ospf cost value undo ospf cost Default The default cost depends on the interface type: 1 for a VLAN interface; 0 for a loopback interface; computed according to the bandwidth for other interfaces with the formula: Interface OSPF cost = Bandwidth reference value (100 Mbps) ÷ Interface bandwidth (Mbps).
Usage guidelines The greater the value, the higher the priority for DR/BDR election. If a device has a priority of 0, it will not be elected as a DR or BDR. Examples # Set the router priority on GigabitEthernet 0/1 to 8. system-view [Sysname] interface gigabitethernet 0/1 [Sysname-GigabitEthernet0/1] ospf dr-priority 8 ospf mib-binding Use ospf mib-binding to bind an OSPF process to MIB operation for responding to SNMP requests. Use undo ospf mib-binding to restore the default.
Default The MTU in DD packets is 0. Views Interface view Default command level 2: System level Usage guidelines After a virtual link is established via a Virtual-Template, two devices on the link from different vendors may have different MTU values. To make them consistent, set the attached interfaces' MTU to the default value 0. After you configure this command, the interface checks whether the MTU in a received DD packet is greater than its own MTU. If yes, the interface discards the packet.
Usage guidelines If a router on a broadcast network does not support multicast, configure the network type for the connected interfaces as NBMA. If any two routers on an NBMA network are directly connected via a virtual link—the network is fully meshed, you can configure the network type for the connected interfaces as NBMA. If two routers are not directly connected, you must configure the P2MP network type so that the two routers can exchange routing information via another router.
Use undo ospf timer dead to restore the default. Syntax ospf timer dead seconds undo ospf timer dead Default The dead interval is 40 seconds for broadcast and P2P interfaces and is 120 seconds for P2MP and NBMA interfaces. Views Interface view Default command level 2: System level Parameters seconds: Specifies the dead interval in seconds, in the range of 1 to 2147483647.
Parameters seconds: Specifies the hello interval in seconds, in the range of 1 to 65535. Usage guidelines The shorter the hello interval is, the faster the topology converges and the more resources are consumed. Make sure the hello interval on two neighboring interfaces is the same. Examples # Configure the hello interval on GigabitEthernet 0/1 as 20 seconds.
ospf timer retransmit Use ospf timer retransmit to set the LSA retransmission interval on an interface. Use undo ospf timer retransmit to restore the default. Syntax ospf timer retransmit interval undo ospf timer retransmit Default The LSA retransmission interval is 5 seconds. Views Interface view Default command level 2: System level Parameters interval: Specifies the LSA retransmission interval in seconds, in the range of 1 to 3600.
Parameters seconds: Specifies the LSA transmission delay in seconds, in the range of 1 to 3600. Usage guidelines Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not change during transmission. It is necessary to add a transmission delay into its age time on low speed networks. Examples # Set the LSA transmission delay to 3 seconds on GigabitEthernet 0/1.
Related commands ospf dr-priority preference Use preference to set a preference for OSPF routes. Use undo preference to restore the default. Syntax preference [ ase ] [ route-policy route-policy-name ] value undo preference [ ase ] Default The preference is 10 for OSPF internal routes and 150 for OSPF external routes (or ASE routes). Views OSPF view Default command level 2: System level Parameters ase: Sets a preference for OSPF external routes.

The default is 5000. Usage guidelines Based on the LSDB, an OSPF router uses SPF to calculate a shortest path tree with itself being the root. OSPF uses the shortest path tree to determine the next hop to a destination.
To configure an area as a stub area, issue the stub command on all routers attached to the area. Examples # Configure Area 1 as a stub area. system-view [Sysname] ospf 100 [Sysname-ospf-100] area 1 [Sysname-ospf-100-area-0.0.0.1] stub Related commands default-cost stub-router Use stub-router to configure a router as a stub router. Use undo stub-router to restore the default. Syntax stub-router undo stub-router Default No router is configured as a stub router.
undo transmit-pacing Default An OSPF interface sends up to three LSU packets every 20 milliseconds. Views OSPF view Default command level 2: System level Parameters interval interval: Specifies an interval at which an interface sends LSU packets, in the range of 10 to 1000 milliseconds. If the router has multiple OSPF interfaces, increase this interval to reduce the total number of LSU packets sent by the router every second.
trans-delay seconds: Sets the transmission delay interval in seconds, in the range of 1 to 3600. The default is 1. dead seconds: Sets the dead interval in seconds, in the range of 1 to 32768. The default is 40. It must be identical to that on the virtual link neighbor. The dead interval is at least four times the hello interval. md5: Enables MD5 authentication. hmac-md5: Enables HMAC-MD5 authentication. simple: Enables simple authentication.
BGP configuration commands For more information about routing policy configuration commands in this document, see "Routing policy configuration commands." The term "router" in this document refers to both routers and LB module. aggregate Use aggregate to create a summary route in the BGP routing table. Use undo aggregate to remove a summary route.
Keywords Function detail-suppressed This keyword does not suppress the summary route, but it suppresses the advertisement of all the more specific routes. To summarize only some specific routes, use the peer filter-policy command. suppress-policy Used to create a summary route and suppress the advertisement of some summarized routes. If you want to suppress some routes selectively and leave other routes still advertised, use the if-match clause of the route-policy command.
Usage guidelines Unlike IGP, BGP has no explicit metric for making load balancing decision. Instead, it implements load balancing by using route selection rules. If you do not provide the ibgp or the ebgp keyword, this command configures load balancing for all BGP routes. After you execute the balance ibgp number or the balance ebgp number command, the balance number command cannot be executed.

Usage guidelines When the link to a directly connected EBGP peer is down, the router, with quick EBGP session reestablishment enabled, tears down the session to the peer, and then immediately reestablishes a session. If the function is not enabled, the router does not tear down the session until the holdtime times out. A route flap does not affect the EBGP session state when the quick EBGP session reestablishment is disabled. Examples # In BGP view, enable quick reestablishment of direct EBGP session.
• To deny/permit a route with the specified destination and mask, use rule [ rule-id ] { deny | permit } ip source sour-addr sour-wildcard destination dest-addr dest-wildcard. The source keyword specifies the destination address of a route, and the destination keyword specifies the subnet mask of the route. (The subnet mask must be valid; otherwise, the configuration is ineffective.) Examples # In BGP view, reference ACL 2000 to filter all outgoing routes.

IPv6 BGP configuration commands For more information about routing policy configuration commands in this document, see "Routing policy configuration commands." The term "router" in this document refers to both routers and LB module. aggregate (IPv6 address family view) Use aggregate to create an IPv6 summary route in the IPv6 BGP routing table. Use undo aggregate to remove an IPv6 summary route.
Keywords Function detail-suppressed This keyword does not suppress the summary route, but it suppresses the advertisement of all the more specific routes. To summarize only some specific routes, use the peer filter-policy command. suppress-policy Used to create a summary route and suppress the advertisement of some summarized routes. If you want to suppress some routes selectively and leave other routes still advertised, use the if-match clause of the route-policy command.
If you do not provide the ibgp or the ebgp keyword, this command configures load balancing for all IPv6 BGP routes. After you execute the balance ibgp number or the balance ebgp number command, the balance number command cannot be executed. To execute the balance number command, you must first use the undo form of the balance ibgp number or balance ebgp number command to remove the former configuration. Examples # Set the number of IPv6 BGP ECMP routes to 2.
