Page 33: Flow-Control Receive Enable
View Ethernet interface view Default level 2: System level Parameters None Description Use the flow-control command to enable TxRx mode generic flow control on an Ethernet interface. Use the undo flow-control command to disable generic flow control on the Ethernet interface. TxRx mode flow control enables an Ethernet interface to receive common pause frames from its peer, and send common pause frames to notify its peer of congestions.
Page 34: Flow-Interval
By default, Rx flow control is disabled on Ethernet interfaces. With the flow-control receive enable command configured, an interface can receive, but not send flow control frames. When the interface receives a flow control frame from its peer, it suspends sending packets to the peer.

Page 41: Loopback-Detection Interval-Time
Description Use the loopback-detection enable command to enable loopback detection globally in system view or on ports in Ethernet interface or port group view. To use loopback detection on an Ethernet port, you must enable the function both globally and on the port. Use the undo loopback-detection enable command to disable loopback detection globally or on ports.

Related commands: loopback-detection enable, loopback-detection interval-time, loopback-detection control enable, loopback-detection per-vlan enable, and loopback-detection action. NOTE: To enable multi-port loopback detection, you must configure the loopback-detection multi-port-mode enable and loopback-detection enable commands in system view, and the loopback-detection enable command in the view of the related interfaces. Examples # Enable multi-port loopback detection to monitor loops between GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2.

H3C does not recommend you to set the forward delay by using this command. Instead, you can use the stp bridge-diameter command to set the network diameter and let MSTP automatically calculates the forward delay according to the network size.
Page 141: Stp Timer Max-Age
BPDU timeout. H3C does not recommend you to set the hello time by using this command. Instead, you can use the stp bridge-diameter command to set the network diameter and let MSTP automatically calculates the hello time according to the network size.
Page 142: Stp Timer-Factor
H3C does not recommend you to set the max age by using this command. Instead, you can use the stp bridge-diameter command to set the network diameter and let MSTP automatically calculates the max age according to the network size. When the network diameter is the default value, the max age is also set to the default.
Page 143: Stp Transmit-Limit
A larger maximum transmission rate value requires more system resources. An appropriate maximum transmission rate setting can limit the speed at which a port sends BPDUs and prevent MSTP from using excessive bandwidth resources during network topology changes. H3C recommends that you use the default value.
Page 144 Parameters modulo: Sets the modulo value, ranging from 1 to 16. Description Use the vlan-mapping modulo command to map VLANs in the current MST region to MSTIs according to the specified modulo value, quickly creating a VLAN-to-instance mapping table. By default, all VLANs are mapped to the CIST (MSTI 0). You cannot map the same VLAN to different MSTIs.

Page 160 For more information about Layer 2 aggregate interfaces, see the Layer 2—LAN Switching Configuration Guide. H3C recommends that you set the same default VLAN ID for the local and remote hybrid ports. After configuring the default VLAN for a hybrid port, you must use the port hybrid vlan command to configure the hybrid port to allow packets from the default VLAN to pass through, so that the port can forward packets from the default VLAN.

Page 166: Mac Address-Based Vlan Configuration Commands
After configuring the default VLAN for a trunk port, you must use the port trunk permit vlan command to configure the trunk port to allow packets from the default VLAN to pass through, so that the port can forward packets from the default VLAN. Related commands: port link-type and port trunk permit vlan.

Examples # Enable MAC address-based VLAN on GigabitEthernet 1/0/1.
Page 170: Mac-Vlan Trigger Enable
After associate MAC addresses with a VLAN, if you specifies the 802.1p priority value corresponding to the specified MAC address, you still need to use the qos trust dot1p command in interface view to configure the interface to use the 802.1p priority in incoming packets for priority mapping. For details about this command, see the ACL and QoS Command Reference.

Page 172: Protocol-Based Vlan Configuration Commands
By default, VLANs are matched based on MAC addresses preferentially. This command only applies to VLANs based on a single MAC address and IP subnet-based VLANs. If both the MAC address-based VLAN function and the IP subnet-based VLAN function are created on a port, MAC address-to-VLAN mappings are matched preferentially, and the left VLAN entries (VLAN entries based on a single MAC address and IP subnet-based VLANs) are matched as configured by the vlan precedence command.

Default level 2: System level Parameters None Description Use the lldp encapsulation snap command to configure the encapsulation format for LLDPDUs as SNAP on a port or a group of ports. Use the undo lldp encapsulation command to restore the default encapsulation format for LLDPDUs. By default, Ethernet II encapsulation applies.
Page 233: Lldp Hold-Multiplier
lldp hold-multiplier Syntax lldp hold-multiplier value undo lldp hold-multiplier View System view Default level 2: System level Parameters value: Sets the TTL multiplier, ranging from 2 to 10. Description Use the lldp hold-multiplier command to set the TTL multiplier. Use the undo lldp hold-multiplier command to restore the default. By default, the TTL multiplier is 4.
Page 234: Lldp Management-Address-Tlv
Use the undo lldp management-address-format command to restore the default. By default, the management address is encapsulated in the form of numbers in TLVs. Examples # Configure GigabitEthernet 1/0/1 to encapsulate the management address in the form of strings in management address TLVs.
Page 235: Lldp Notification Remote-Change Enable
lldp notification remote-change enable Syntax lldp notification remote-change enable undo lldp notification remote-change enable View Layer 2 Ethernet interface view, port group view Default level 2: System level Parameters None Description Use the lldp notification remote-change enable command to enable LLDP trapping for a port or all the ports in a port group.
Page 236: Lldp Timer Reinit-Delay
<Sysname> system-view [Sysname] lldp timer notification-interval 8 lldp timer reinit-delay Syntax lldp timer reinit-delay delay undo lldp timer reinit-delay View System view Default level 2: System level Parameters delay: Sets the LLDP re-initialization delay, ranging from 1 to 10 seconds. Description Use the lldp timer reinit-delay command to set the LLDP re-initialization delay.
Page 237: Lldp Timer Tx-Interval
Examples # Set the LLDPDU transmit delay to 4 seconds. <Sysname> system-view [Sysname] lldp timer tx-delay 4 lldp timer tx-interval Syntax lldp timer tx-interval interval undo lldp timer tx-interval View System view Default level 2: System level Parameters interval: Sets the LLDPDU transmit interval, ranging from 5 to 32768 seconds. Description Use the lldp timer tx-interval command to set the LLDPDU transmit interval.
Page 238 Parameters all: Advertises all the basic LLDP TLVs, all the IEEE 802.1 organizationally specific LLDP TLVs, or all the IEEE 802.3 organizationally specific LLDP TLVs when the all keyword is specified for basic-tlv, dot1-tlv, or dot3-tlv, or advertises all the LLDP-MED TLVs except location identification TLVs when the all keyword is specified for med-tlv.
Page 239 Description Use the lldp tlv-enable command to configure the types of advertisable TLVs for a port or all the ports in a port group. Use the undo lldp tlv-enable command to disable the advertising of specific types of TLVs. By default, all types of LLDP TLVs, except location identification TLVs, are advertisable on a Layer 2 Ethernet port.
