Redback Usage Guide

Ping

ping address [number] [size bytes] [timeout seconds]
Description
The ping command tests the IP-accessibility of a host.

Syntax Description
  • ip-address | hostname The IP address of the host or the hostname. DNS must be enabled in order to use the hostname argument. Refer to the Usage Guidelines.
  • number-of-packets Optional. The number of ping packets to send. The valid range is 1 through 10000; the default is 5.
  • interface name Optional. Specifies the name of the interface from which ping packets are sourced. Uses the primary address of the interface, which must be in the UP state, as the source of ping packets.
  • src ip-address Optional. Specifies the IP source address of the ping packets. An interface with this IP address must exist.
  • pattern hex-pattern Optional. Specifies a hex pattern to fill in Internet Control Message Protocol (ICMP) packets. The range is 0x0 through 0xffffffff.
  • size bytes Optional. The size of each IP packet in bytes. The valid range is 40 through 18432; the default is 100.
  • timeout seconds Optional. The time in seconds that the system will wait for a response for each ping packet. The valid range is 1 through 100; the default is 2.
Example
The following example sends five ping packets to host 10.1.1.1:
[local]RedBack>ping 10.1.1.1
Sending 5, 100-byte ICMP echoes to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms
The following example sends three ping packets, each 1000 bytes in size, to host 10.1.1.1:
[local]RedBack>ping 10.1.1.1 3 size 1000
Sending 3, 1000-byte ICMP echoes to 10.1.1.1, timeout is 2 seconds:
!!!
Success rate is 100 percent (3/3), round-trip min/avg/max = 0/1/2 ms

Traceroute

traceroute address [timeout seconds] [count number] [ttl ttl] [port port] [size bytes]
Description
The traceroute command traces the IP route to a given destination.

Syntax Description
  • ip-address | hostname The IP address or hostname to be traced. DNS must be enabled in order to use the hostname argument. Refer to the Usage Guidelines.
  • count number Optional. The number of probes to send.The valid range is 1 through 1000; the default is 3.
  • df Optional. Sets the “Don’t Fragment” bit on outbound traceroute packets. With this bit set, the traceroute packet is dropped whenever it would normally be fragmented. An ICMP “Unreachable, Needs Fragmentation” packet is sent to the sender.
  • maxttl ttl Optional. The maximum time to live. The valid range is 1 through 255; the default is 30.
  • minttl ttl Optional. The minimum time to live. The valid range is 1 through 255; the default is 1.
  • port port Optional. The destination UDP port number. The valid range is 1 through 65535; the default is 33434.
  • size bytes Optional. The datagram size in octets. The valid range is 40 through 2000; the default is 140.
  • src ip-address Optional. Specifies the IP source address of the ping packets. An interface with this IP address must exist.
  • timeout seconds Optional. The timeout value in seconds for each probe sent. The valid range is 1 through 1000; the default is 2.
Example
The following example detects the route from the local context to the IP address 206.124.29.1, using 100-byte packets, UDP port 73, ttl 20, timeout 3, and count 3.

Clear Commands

clear circuit

clear circuit {slot/port {vpi vci | [hdlc-channel] dlci | all} | pppoe {session-id | all}}
Description
The clear circuit command returns the specified circuit in the indicated port or HDLC channel to the unconfigured state.

Syntax Description
  • slot/port Backplane slot number and port number of an ATM or Frame Relay port.
  • vpi Virtual Path Identifier of the circuit. The valid range is 0 through 255.
  • vci Virtual Channel Identifier of the circuit. For ATM T1 modules, the valid range is 1 through 1023; for ATM DS-3 Version 1 modules, the valid range is 1 through 2047; for ATM OC-3 Version 1 modules, the valid range is 1 through 4095; for all ATM Version 2 modules, the valid range is 1 through 65535.
  • hdlc-channel Name of the HDLC channel in the case for a Channelized DS-3 port. This argument is required for Channelized DS-3 modules and not allowed in any other case.
  • dlci DLCI number of a configured Frame Relay PVC.
  • pppoe {session-id | all} Specifies that pppoe circuits are to be cleared.
  • cm slot The slot number of the Connection Manager (CM) module for the session. Specified only for the SMS 10000 hardware platform.
  • all With the slot/port argument, specifies that all circuits on the specified slot and port are to be cleared.

Example
The following example clears all active subscriber sessions on all circuits in the specified slot/port:
[local]RedBack#clear circuit 3/0 all
[local]RedBack#

clear subscriber

clear subscriber subscriber
Description
The clear subscriber command disconnects a given subscriber in the current context.

Syntax Description
  • name The name of the subscriber to be cleared, in any valid structured username format.

Example
To clear the subscriber, npt0005.0.241@veriomail.com :
[local]RedBack>clear subscriber npt0005.0.241@veriomail.com
[local]RedBack>

clear port counters

clear port counters slot/port [hdlc-channel name] [pvc {all | vpi [vci [through end-vci]] 
  | dlci [through end-dlci]}] [-noconfirm]
Description
Clears the counters associated with the specified port, the specified PVCs within a port, or the specified channels within a port. This command is replacing the older command, clear counters.

Syntax Description
  • slot/port Physical backplane slot number and the specific port number on a particular module.
  • hdlc-channel name Optional. Used to clear counters associated with a specific HDLC channel, or a PVC within a specific channel. This option is only available for channelized DS-3 ports.
  • pvc Optional. Used to clear counters associated with all PVCs, a specific PVC, PVCs associated with a specific virtual path identifier (VPI) or a range of PVCs. This option is valid only for ATM and Frame Relay ports.
  • all Optional. Used to clear counters associated with all PVCs on the port.
  • vpi Optional. Specifies the virtual path identifier. This option is valid only for ATM ports. The valid range is 0 through 255.
  • vci Optional. Specifies the virtual circuit identifier, or the beginning of a range of vcis. For ATM T1 modules, the valid range is 1 through 1023; for ATM DS-3 Version 1 modules, the valid range is 1 through 2047; for ATM OC-3 Version 1 modules, the valid range is 1 through 4095; for all ATM Version 2 modules, the valid range is 1 through 65535.
  • through end-vci Optional. Specifies last virtual channel identifier in a range of PVCs for which counters should be cleared.
  • dlci Optional. DLCI number of a configured Frame Relay PVC. This option is valid only for Frame Relay ports.
  • through end-dlci Optional. Specifies last DLCI in a range of PVCs for which counters should be cleared.
  • -noconfirm Optional. When used with this option, the command takes effect without requesting confirmation from the user.

Example
To clear the counters for the ATM port located in slot 4 port 1: 
[local]RedBack#clear counters atm 4/1 -noconfirm
To clear the counters for the same port for PVCs in the range from 18:100 to 18:200 
[local]RedBack#clear counters atm 4/1 pvc 18 100 through 200 -noconfirm
To clear counters without the -noconfirm option: 
[local]RedBack#clear counters atm 5/0 pvc 1 1
clear pvc counters for atm port 5/0 vpi 1 vci 1 [confirm] y

ATM Ping Commands

atm ping {path | channel} {segment | end-to-end} slot/port vpi [vci] [count number] 
  [timeout seconds]
Description
Tests virtual circuits by sending operation, administration, and maintenance (OAM) loopback cells.

Syntax Description
  • path Sends F4 OAM loopback cells down the specified virtual path connection.
  • channel Sends F5 OAM loopback cells down the specified virtual channel connection.
  • segment Sends OAM loopback cells to a neighbor switch.
  • end-to-end Sends OAM loopback cells to the end of the connection where ATM cells are terminated.
  • slot/port Specifies the backplane slot number and port number of an ATM port.
  • vpi Specifies the virtual path identifier. The valid range is 0 through 255.
  • vci Optional. Specifies the virtual channel identifier. This argument must be specified with the channel keyword, and is not allowed with the path keyword. For ATM T1 modules, the valid range is 1 through 1023; for ATM DS-3 Version 1 modules, the valid range is 1 through 2047; for ATM OC-3 Version 1 modules, the valid range is 1 through 4095; for all ATM Version 2 modules, the valid range is 1 through 65535.
  • count number Optional. Specifies the number of OAM cells to send. The valid range is 1 through 10000; the default is 5.
  • timeout seconds Optional. Specifies the time in seconds that AOS will wait for a response for each OAM ping. The valid range is 1 through 100; the default is 2.
Example
The following example sends the default 5 cells to the customer located on Card 4, Port 1, VPI 1, VCI 421.
[local]n00.nworla01.us.ra#atm ping channel segment 4/0 1 421

Sending 5, segment F5 cells on 4/0, 1:421, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5)
[local]n00.nworla01.us.ra#
The following example sends sixteen end-to-end F5 cells on VPI:VCI 2:47 using the ATM port in slot 5, port 0:
[local]RedBack>atm ping channel end-to-end 5/0 2 47 count 16
Sending 16, end-to-end F5 cells on 5/0, 2:47, timeout is 2 seconds:
!!!!!!!!!!!!!!!!
Success rate is 100 percent (10/10)
