View
Layer-2 aggregate interface view
Default Level
2: System level
Parameters
text: Description of an Ethernet interface, a string of 1 to 80 characters. Currently, the device supports the following types of characters or symbols: standard English characters (numbers and case-sensitive letters), special English characters, spaces, and other characters or symbols that conform to the Unicode standard.
l A port description can be the mixture of English characters and other Unicode characters. The mixed description cannot exceed the specified length.
l To use a type of Unicode characters or symbols in a port description, you need to install the corresponding Input Method Editor (IME) and log in to the device through remote login software that supports this character type.
l Each Unicode character or symbol (non-English characters) takes the space of two regular characters. When the length of a description string reaches or exceeds the maximum line width on the terminal software, the software starts a new line, possibly breaking a Unicode character into two. As a result, garbled characters may be displayed at the end of a line.
Description
Use the description command to set the description of the current interface.
Use the undo description command to restore the default.
By default, the description of an interface is interface-name Interface, such as Bridge-Aggregation1 Interface.
Examples
# Set the description of interface Bridge-aggregation 1 to link-aggregation interface.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] description link-aggregation interface

display link-aggregation member-port
Syntax
display link-aggregation member-port [ interface-type interface-number [ to interface-type interface-number ] ]
View
Any view
Default Level
1: Monitor level
Parameters
interface-type interface-number: Port type and port number.
to: Specifies an interface range in the form of interface-type interface-number to interface-type interface-number, where the start interface number must be smaller than the end interface number. Note that both the start interface and the end interface are inclusive.
Description
Use the display link-aggregation member-port command to display the detailed link aggregation information of the specified interface(s) or all interfaces if no interface is specified.
For an interface in a static aggregation group, only its port number and operational key are displayed, because it is not aware of the information of the partner.
Examples
# Display the detailed link aggregation information of Ethernet 2/0/1, which is in a static aggregation group.
<Sysname> display link-aggregation member-port ethernet 2/0/1

Parameters

Description
Use the display link-aggregation summary command to display the summary information of all aggregation groups.
You may find out that information about the remote system for a static link aggregation group is either replaced by none or not displayed at all. This is normal because this type of aggregation group is not aware of its partner.

enable snmp trap updown
Syntax
enable snmp trap updown
undo enable snmp trap updown
View
Layer-2 aggregate interface view
Default Level
2: System level
Parameters
None
Description
Use the enable snmp trap updown command to enable linkUp/linkDown trap generation for the current aggregate interface.
Use the undo enable snmp trap updown command to disable linkUp/linkDown trap generation for the current aggregate interface.
By default, linkUp/linkDown trap generation is enabled for an aggregate interface.
Note that for an aggregate interface to generate linkUp/linkDown traps when its link state changes, you must also enable linkUp/linkDown trap generation globally with the snmp-agent trap enable [ standard [ linkdown | linkup ] * ] command.
Refer to SNMP Commands in the System Volume for information about the snmp-agent trap enable command.
Examples
# Enable linkUp/linkDown trap generation on interface Bridge-aggregation 1.
<Sysname> system-view
[Sysname] snmp-agent trap enable
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] enable snmp trap updown

Default Level
2: System level
Parameters
interface-number: Layer-2 aggregate interface number. The value range is 1 to 1,024..
Description
Use the interface bridge-aggregation command to create a Layer-2 aggregate interface and enter the Layer-2 aggregate interface view.
Use the undo interface bridge-aggregation command to remove a Layer-2 aggregate interface.
Upon creation of a Layer-2 aggregate interface, a Layer-2 aggregation group numbered the same is created automatically. Removing the Layer-2 aggregate interface also removes the Layer-2 aggregation group. At the same time, the member ports of the aggregation group, if any, leave the aggregation group.
Examples
# Create Layer-2 aggregate interface Bridge-aggregation 1.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1]
