Cellular interface view

Predefined user roles

network-admin

Parameters

at-string: Specifies a configuration directive string, a string of 1 to 300 characters. This argument can be an AT directive (containing +++, A/, or be any string beginning with AT) or a CNS directive. For more information about AT directives, see the sendat command in modem management commands in Network Connectivity Command Reference. Table 3 describes the CNS directive samples.

Table 3 CNS directive description

Directive	Description
CNSn	Controls the CNS heartbeat debugging switch. ·     n = 00000500000000000000—Enables CNS heartbeat debugging. ·     n = 00000800000000000000—Disables CNS heartbeat debugging.

 

Usage guidelines

The sendat command does not verify the configuration directive. Each time it issues one configuration directive to the 4G modem, lowercase characters are automatically converted to uppercase characters.

One sendat command issues one configuration directive. To issue multiple configuration directives to a modem, you must repeat the sendat command.

Configuration directives might cause malfunction of a 4G modem. When you issue a configuration directive to the modem, make sure you understand the impact on the 4G modem.

Output queue - Protocol queuing: Size/Length/Discards	Packet statistics for protocol queuing in the output queue of the interface: ·     Size—Current number of packets in the queue. ·     Length—Maximum number of packets that can stay in the queue. ·     Discards—Number of dropped packets.
Output queue - FIFO queuing: Size/Length/Discards	Packet statistics for FIFO queuing in the output queue of the interface: ·     Size—Current number of packets in the queue. ·     Length—Maximum number of packets that can stay in the queue. ·     Discards—Number of dropped packets.
Last link flapping	The amount of time that has elapsed since the most recent physical state change of the interface. This field displays Never if the interface has been physically down since device startup.
Last clearing of counters	Time when statistics on the logical interface were last cleared by using the reset counters interface command. If statistics about the interface have never been cleared by using the reset counters interface command since the device started, this field displays Never.
Last 300 seconds input rate	Average input rate during the last 300 seconds: ·     bytes/sec—Average number of received bytes per second. ·     bits/sec—Average number of received bits per second. ·     packets/sec—Average number of received packets per second.
Last 300 seconds output rate	Average output rate over the last 300 seconds: ·     bytes/sec—Average number of sent bytes per second. ·     bits/sec—Average number of sent bits per second. ·     packets/sec—Average number of sent packets per second.
Input: 0 packets, 0 bytes, 0 buffers	Incoming packet statistics: ·     0 packets—Packet number. ·     0 bytes—Packet size in bytes. ·     0 buffers—Number of buffered units.
Output: 0 packets, 0 bytes	Outgoing packet statistics: ·     0 packets—Packet number. ·     0 bytes—Packet size in bytes.
Link	Physical link state of the interface: ·     UP—The interface is physically up. ·     DOWN—The interface is physically down. ·     ADM—The interface has been shut down by using the shutdown command. To restore the physical state of the interface, use the undo shutdown command. ·     Stby—The interface is a backup interface in standby state. To see the primary interface, use the display interface-backup state command.
Protocol	Data link layer protocol state of the interface: ·     UP—The data link layer protocol of the interface is up. ·     DOWN—The data link layer protocol of the interface is down. ·     UP(s)—The data link layer protocol of the interface is up, but the link is an on-demand link or does not exist. The (s) attribute represents the spoofing flag. This value is typical of null interfaces and loopback interfaces.
Main IP	Main IP address of the interface.
Description	Description of the interface.
Cause	Cause for the physical link state of the interface to be DOWN. The value of the field varies by device model. Administratively represents that the interface has been manually shut down by using the shutdown command. To restore the physical state of the interface, use the undo shutdown command.

 

eth-channel

Parameters

interface-number: Specifies an Eth-channel interface by its number.

Examples

# Enter Eth-channel 1/0/6:0 interface view.

<Sysname> system-view

[Sysname] interface eth-channel 1/0/6:0

[Sysname-Eth-channel1/0/6:0]

mtu

Use mtu to set the maximum transmission unit (MTU) for an interface.

Use undo mtu to restore the default.

Syntax

mtu size
