8-Port E3/DS3 ATM Line Card Configuration
This chapter describes procedures for configuring the Cisco 10000 series 8-Port E3/DS3 ATM line card, hereafter known as the 8-Port E3/DS3 ATM line card.
The 8-Port E3/DS3 ATM line card has eight E3 or DS3 (T3) copper interface terminations that provide Asynchronous Transfer Mode (ATM) serial interfaces and perform Layer 2 ATM functions.
This chapter contains the following sections:

Line Card Interface Configuration Examples
Software Support
Table 2-1 shows the minimum Cisco IOS release on each release train that supports the 8-Port E3/DS3 ATM line card.
Checking Hardware and Software Compatibility
The PRE installed in the Cisco 10000 series router chassis must support the Cisco IOS software running on the router. Use the show version command to check the PRE version installed.
To see if a feature is supported by a Cisco IOS release, to locate the software document for that feature, or to check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl
This tool does not verify whether line cards within a system are compatible, but does provide the minimum Cisco IOS requirements for individual hardware line cards, modules, or options.
You must be a registered user on Cisco.com to access this tool.
Default Values
Table 2-2 lists default configuration values for the 8-Port E3/DS3 ATM line card. This table also includes the commands used to modify a default values, and provides information about values to set on the remote end of the connection.
Line Card VC Limitations
The Cisco 10000 series router supports four ATM service categories for virtual circuits (VCs):
•
•
•
•
The segmentation and reassembly (SAR) mechanism configures priority and additional traffic management parameters for the various ATM service categories. Table 2-3 lists the priority levels the SAR sets for the service categories.
Table 2-3 ATM Service Categories
Priority
0
1
2
3
None
The number of SAR priority levels and the service categories supported at each priority level vary from line card to line card. For example, the 8-port E3/DS3 supports the two levels of priority and the service categories listed in the Table 2-4.
The ATM line cards support a maximum number of VCs per priority. That VC limit depends on the VC limit of the SAR (SAR limit) and the number of priority levels configured. Table 2-4 describes how to determine the VC limit per priority level per port for the 8-port E3/DS3 line card.
Configuring more channels or VCs than there are available priority locations can cause random channels or VCs to get stuck in the SAR. This occurs when an active channel tries to reschedule itself, but no priority locations are available. Therefore, the channel cannot find a place to reschedule itself, which results in a lost event for the channel, and the channel becomes stuck in the SAR.
On the PRE2, when a VC becomes stuck in the SAR, the PRE2 scheduler stops forwarding traffic on only the VC that is stuck in the SAR; the other VCs still carry traffic. On the PRE3, the PRE3 scheduler stops forwarding traffic on all the VCs configured on that ATM line card.
Interface Syntax
To specify an interface number in a configuration command, use the syntax in Table 2-5 to identify interfaces and subinterfaces on the 8-Port E3/DS3 ATM line card in the Cisco series 10000 router.
Examples:
•
Router(config)# interface atm 2/0/0Router(config-if)# pvc 0/200Router(config-if-atm-vc)#•
Router(config)# interface atm 7/0/0.1Router(config-subif)# pvc 0/101Router(config-if-atm-vc)#Line Card Interface Configuration Examples
This section provides sample procedures for configuring the 8-Port E3/DS3 ATM line card for E3 or T3 connections, as well as creating ATM subinterfaces, permanent virtual circuits (PVCs), and virtual circuit (VC) classes. Procedures for enabling Integrated Local Management Interface (ILMI) are also included.
Creating a Subinterface
Use the following procedure to create a subinterface on an 8-Port E3/DS3 ATM line card interface.
Step 1
In the following example, multipoint subinterface number 1 is created on port 0 of the 8-Port E3/DS3 ATM line card in slot 2.
Router(config)# interface atm 2/0/0.1 multipointRouter(config-subif)#Step 2
Router(config-subif)# ip address 172.27.48.209 255.255.0.0You created ATM subinterface 2/0/0.1. To configure or modify this interface, use the following command:
Router(config)# interface atm 2/0/0.1Router(config-subif)#Creating a PVC
You can create multiple PVCs on an 8-Port E3/DS3 ATM line card interface. You can create PVCs on an interface or subinterface.
To create a PVC, perform the following steps:
Step 1
Use the pvc command to specify a virtual path identifier (VPI) value between 0 and 255 and a virtual channel identifier (VCI) value between 0 and 65535. The following example shows how to create a PVC with a VPI value of 0 and VCI value of 100 on a subinterface.
Router(config-subif)# pvc 0/100Router(config-if-atm-vc)#Step 2
Router(config-if-atm-vc)# protocol ip 172.16.32.49Router(config-if-atm-vc)#
Creating an ATM VC Class
This procedure demonstrates how to create an ATM VC class. An ATM VC class is a PVC boilerplate—a PVC description that you can apply to one or more PVCs.
To create an ATM VC class, perform the following steps:
Step 1
Router(config)# vc-class atm bostonRouter(config-vc-class)#Step 2
Router(config-vc-class)# encapsulation aal5mux ipRouter(config-vc-class)# vbr-nrt 30000 20000 128Router(config-vc-class)# exitRouter(config)#You have created a VC class named boston. The next procedure describes steps for applying this class to a PVC or subinterface.
Applying a VC Class
You can apply a VC class (created in the previous procedure) to a PVC or a subinterface.
•
Router(config)# interface atm 5/0/0.2Router(config-subif)# pvc 0/102Router(config-if-atm-vc)# class-vc bostonRouter(config-if-atm-vc)#•
Router(config)# interface atm 5/0/0.1Router(config-subif)# class-int bostonRouter(config-subif)#You have completed the steps for assigning a VC class to a PVC.
Enabling ILMI PVC Discovery
You can enable ILMI to automatically discover PVCs on neighboring switches and duplicate those PVC entries on the 8-Port E3/DS3 ATM line card.
To enable ILMI, perform the following steps:
Step 1
Router(config)# interface atm 5/0/0Router(config-if)# pvc 0/16 ilmiRouter(config-if-atm-vc)# exitRouter(config-if)#Step 2
Router(config-if)# atm ilmi-pvc-discoveryYou have completed the steps required to run ILMI PVC discovery. You can use the show atm pvc command to display the PVCs on the Cisco 10000 series router.

To check your completed configuration, use the show commands. For more information about show commands, see Useful show Commands.
Line Card Commands
The 8-Port E3/DS3 ATM line card allows you to specify eight E3 or eight T3 interfaces. You can put all the PVCs on the interfaces, or you can create associated subinterfaces. This section describes the principal commands for customizing interfaces and PVCs:
•
•
Global Configuration Commands
A PVC boilerplate is a PVC description that you can apply to one or more PVCs or interfaces.
To create a PVC boilerplate, use the vc-class atm command in global configuration mode:
vc-class atm class_name
Where class_name is any value that describes the VC class.
After you enter the vc-class atm command, you enter VC class configuration mode. In this mode, you describe the action you want the class to take by entering commands and their arguments. These commands and arguments are described in the "ATM PVC Commands" section.
In the following example, an ATM VC class named paris is created and defined. This example shows how to specify that the class uses AAL5+MUX encapsulation and a VBR-NRT PVC.
Router(config)# vc-class atm parisRouter(config-vc-class)# encapsulation aal5mux ipRouter(config-vc-class)# vbr-nrt 30000 20000 128Router(config-vc-class)# exitRouter(config)#For information on applying a VC class name, see the "Attaching an ATM VC Class to an Interface or Subinterface" section and the "Attaching an ATM VC Class to a PVC" section.
ATM Interface and Subinterface Commands
This section describes how to configure ATM interfaces and subinterfaces using the principle commands described in the following sections:
•
•
•
•
•
•
•
•
Setting the Line Card to E3 or T3 mode
You must configure the 8-Port E3/DS3 ATM line card for either E3 or T3 from interface configuration mode.
Note
atm dsx3mode {e3 | t3}{adm | plcp}Where:
adm means ATM direct mapping
plcp means physical layer convergence procedure (PLCP)—specifications that map ATM cells into physical media, such as T3 or E3, and define certain management information.
The default is t3 adm.
In the following example, the 8-Port E3/DS3 ATM line card located in slot 2 is configured for E3 mode with PLCP:
Router(config)# interface atm 2/0/0Router(config-if)# atm dsx3mode e3 plcpChanging the Mode of the Line Card
The 8-Port E3/DS3 ATM line card has four modes (e3 adm, e3 plcp, t3 adm and t3 plcp), the default mode being t3 adm. Each mode has it own bandwidth and cell delay variation tolerance (CDVT) values.
When a line card is freshly inserted, the default mode of the card can be changed. However, if VCs, VPs or subinterfaces have already been configured on the line card, the line card must first be removed and reprovisioned prior to the mode change.
To change the mode of an already provisioned card use the following commands in the configuration mode:
hw-module slot <> shut
no card <>
no hw-module slot <> shut
After the line card is restarted you can change the mode, and re-apply the configurations that were lost during module shutdown.
The following example shows how to change the mode of an already provisioned card, from E3 mode with ADM to E3 mode with PLCP.
Router(config)# hw-module slot 2/0 shutRouter(config)# no card 2/0Router(config)# no hw-module slot 2/0 shutTo change the mode of the line card:
Router(config)# interface atm 2/0/0Router(config-if)# atm dsx3mode e3 plcpTo re-apply the configurations to the line card:
Router(config)#interface atm 2/0/0.1 point-to-pointRouter(config-subif)#pvc 1/100Router(config-if-atm-vc)#vbr-nrt 4000 4000Router(config-if-atm-vc)#endSetting the Line Card Framing
The 8-Port E3/DS3 ATM line card supports ADM and PLCP framing on E3 and T3 connections. The following sections describe how to set T3 ADM, T3 PLCP, E3 ADM, and E3 PLCP framing.
Setting T3 ADM Framing
If you configured the 8-Port E3/DS3 ATM line card for T3 ADM using the atm dsx3mode ds3 adm command, configure the framing using the atm framing command in interface configuration mode.
[no] atm framing {cbitadm | m23adm}Where:
cbitadm is C-bit ADM T3 Framing
m23adm is M23 ADM T3 Framing
The default is cbitadm.
In the following example, M23 ADM T3 framing is set:
Router(config)# interface atm 2/0/0Router(config-if)# atm framing m23admSetting T3 PLCP Framing
If you configured the 8-Port E3/DS3 ATM line card for T3 PLCP using the atm dsx3mode ds3 plcp command, configure the framing using the atm framing command from interface configuration mode.
[no] atm framing {cbitplcp | m23plcp}Where:
cbitplcp is C-bit PLCP T3 Framing
m23plcp is M23 PLCP T3 Framing
The default cbitplcp
In the following example, C-bit PLCP T3 framing is set:
Router(config)# interface atm 2/0/0Router(config-if) atm framing cbitplcpSetting E3 ADM Framing
If you configured the 8-Port E3/DS3 ATM line card for E3 ADM using the atm dsx3mode e3 adm command, configure the framing using the atm framing command in interface configuration mode.
[no] atm framing {g751adm | g832adm}Where:
g751adm is G.751 ADM E3 framing
g832adm is G.832 ADM E3 framing
The default is g751adm.
In the following example, G.751 ADM E3 framing is set:
Router(config)# interface atm 2/0/0Router(config-if)# atm framing g751admSetting E3 PLCP Framing
If you configured the 8-Port E3/DS3 ATM line card for E3 PLCP using the atm dsx3mode e3 plcp command, configure the framing using the atm framing command in interface configuration mode.
[no] atm framing g751plcpWhere g751plcp is G.751 PLCP E3 framing
The default is g751plcp.
In the following example, G.751 PLCP E3 framing is set:
Router(config)# interface atm 2/0/0Router(config-if)# atm framing g751plcpCreating and Entering Subinterfaces
Use the interface command to segment an E3 or T3 ATM main interface into multiple subinterfaces to simplify line card management, to create interfaces with different MTU sizes, and to create connections to different networks.
interface atm slot/subslot/port.subinterface typeno interface atm slot/subslot/port.subinterface typeWhere:
•
•
•
•
•
•
To remove a subinterface and its PVCs, use the no interface command. To change a subinterface type, you must first remove the subinterface.
Examples:
•
Router(config)# interface atm 1/0/3.1 point-to-pointRouter(config-subif)#•
Router(config)# interface atm 1/0/3.1Router(config-subif)#•
If you want multiple PVCs to go to the same network, you must create a multipoint subinterface. For example:
Router(config)# interface atm 4/0/2.2 multipointRouter(config-subif)#After you create the subinterface, you can create PVCs that are attached to the same network. Figure 2-1 shows a multipoint subinterface on a fully meshed network. Fully meshed indicates that any workstation can communicate with any other workstation.
Figure 2-1 Multipoint ATM Configuration
The following examples show the commands used to configure the ATM interfaces for routers A, B, and C (see Figure 2-1), including the configuration commands you must enter to configure the multipoint connections in that network:
Router A
Router(config)# interface atm 4/0/0.2 multiRouter(config-subif)# ip address 131.108.168.1 255.255.255.0Router(config-subif)# pvc 0/35Router(config-if-atm-vc)# protocol ip 131.108.168.2 broadcastRouter(config-if-atm-vc)# exitRouter(config-subif)# pvc 0/36Router(config-if-atm-vc)# protocol ip 131.108.168.3 broadcastRouter(config-if-atm-vc)# exitRouter(config-subif)# exitRouter(config)#Router B
Router(config)# interface atm 2/0/0.1 multiRouter(config-subif)# ip address 131.108.168.2 255.255.255.0Router(config-subif)# pvc 0/35Router(config-if-atm-vc)# protocol ip 131.108.168.1 broadcastRouter(config-if-atm-vc)# exitRouter(config-subif)# pvc 0/37Router(config-if-atm-vc)# protocol ip 131.108.168.3 broadcastRouter(config-if-atm-vc)# exitRouter(config-subif)# exitRouter(config)#Router C
Router(config)# interface atm 5/0/0.1 multiRouter(config-subif)# ip address 131.108.168.3 255.255.255.0Router(config-subif)# pvc 0/36Router(config-if-atm-vc)# protocol ip 131.108.168.1 broadcastRouter(config-if-atm-vc)# exitRouter(config-subif)# pvc 0/37Router(config-if-atm-vc)# protocol ip 131.108.168.2 broadcastRouter(config-if-atm-vc)# exitRouter(config)#Attaching an ATM VC Class to an Interface or Subinterface
Use the class-int command to attach an ATM VC class to an interface or subinterface. If you customize a PVC, that customization takes precedence over the interface class.
class-int class_nameWhere class_name is the name of the class created using the global configuration class-vc atm command.
In the following example, a VC class named paris is created and attached to subinterface 3/0/0.1.
Router(config)# vc-class atm parisRouter(config-vc-class)# encapsulation aal5mux ipRouter(config-vc-class)# vbr-nrt 30000 20000 128Router(config-vc-class)# exitRouter(config)# interface atm 3/0/0.1Router(config-subif)# class-int parisCreating ATM PVPs
To create a permanent virtual path (PVP) used to multiplex one or more VBR-NRT VCs, use the atm pvp interface configuration command.
atm pvp vpi peak-rate [no-f4-oam]no atm pvp vpiWhere:
•
•
•
To verify the configuration of a PVP, use the show atm vp exec command.
The following example shows how to create a PVP with a peak rate of 30,000 kbps. Subsequently, the created VCs are multiplexed onto this virtual path.
Router(config)# interface atm 7/0/0Router(config-if)# atm pvp 25 30000Router(config-if)# pvc 25/100Router(config-if-atm-vc)# vbr-nrt 10000 5000 16Router(config-if-atm-vc)# exitRouter(config-if)# pvc 25/101Router(config-if-atm-vc)# vbr-nrt 10000 5000 16Router(config-if-atm-vc)# exitRouter(config-if)# pvc 25/102Router(config-if-atm-vc)# vbr-nrt 10000 5000 16Router(config-if-atm-vc)# exitRouter(config)#Creating a PVC
This section describes how to create a permanent virtual circuit.
Note
You can establish an unspecified bit rate (UBR) PVC by entering the pvc command:
pvc [word] [vpi_value/]{vci_value} [ilmi]•
•
•
•
•
By default, the pvc command creates a UBR PVC. To specify a VBR-NRT PVC, see the "Configuring VBR-NRT" section.
Examples:
•
Router(config)# interface atm 5/0/0Router(config-if)# pvc 105Router(config-if-atm-vc)#•
Router(config)# interface atm 5/0/0.1Router(config-subif)# pvc 2/102Router(config-if-atm-vc)#Enabling ATM ILMI
Use the atm ilmi-enable interface configuration command to enable ILMI on a port.
atm ilmi-enableno atm ilmi-enableThe default is ILMI is enabled, but you should disable the ILMI if the peer does not support ILMI. For peers to be able to exchange ILMI information, you must create PVC 0/16 using the ilmi argument.
The following example shows how to disable ILMI:
Router(config)# interface atm 5/0/0Router(config-if)# no atm ilmi-enableActivating ATM ILMI PVC Discovery
This command causes ILMI-compliant devices to propagate PVCs. Use the atm ilmi-pvc-discovery command in interface configuration mode to activate ATM PVC discovery.
atm ilmi-pvc-discovery [subinterface]no atm ilmi-pvc-discovery [subinterface]Where:
•
Note
The following example shows how to enable PVC discovery on the ATM interface 7/0/0, for port 0, on an 8-Port E3/DS3 ATM line card that has ILMI enabled.
Router(config)# interface atm 7/0/0Router(config-if)# pvc 0/16 ilmiRouter(config-if-atm-vc)# exitRouter(config-if)# atm ilmi-pvc-discoverySpecifying the ATM ILMI Keep-Alive Rate
Use the atm ilmi-keepalive command to specify the ILMI keep-alive rate.
atm ilmi-keepalive [seconds [retry counts]]Where:
•
•
The default value for seconds is 5000 and for retry counts is 4.
The following example shows how to enable ILMI keepalives for the ATM interface 5/0/0:
Router(config)# interface atm 5/0/0Router(config-if)# atm ilmi-keepalive 10000 retry 3Configuring the ATM Clock
Use the atm clock internal command to configure the clock source as internal.
atm clock {internal | line}no atm clock internalThe default clock setting is no atm clock internal, which means that clocking is derived from the line.
In the following example, clocking is set to internal.
Router(config)# interface atm 5/0/0Router(config-if)# atm clock internalConfiguring Cable Length
The atm lbo command improves signal strength for losses associated with lengthy cables. To specify whether the cable attached to the interface is short or long, use the atm lbo command in the following format:
atm lbo {short | long}Where:
short is for a cable that is less than 225 feet.
long is for a cable that is 225 feet or greater.
The default is short.
In the following example, the cable length is set to short:
Router(config)# interface 2/0/0Router(config-controller)# atm lbo shortControlling ATM Alarm Reporting
To control alarms so that they are logged to the console for an ATM interface, use the atm report command in interface configuration mode.
atm report {los | oof | ais | ferf | lcd}no atm report {los | oof | ais | ferf | lcd}Where:
•
•
•
•
•
To disable logging of alarms, use the no form of this command.
Reporting an alarm means that the alarm can be logged to the console. Not all alarms are logged. The alarm hierarchy rules dictate that only the most severe alarm of an alarm group is reported. Whether an alarm is reported or not, you can view the current state of a defect by checking the Active Defects line from the show controllers atm command output.
The following example shows how to enable reporting of SD-BER and AIS alarms on the interface:
Router(config)# interface atm 3/0/0Router(config-if)# atm report losRouter(config-if)# atm report aisRouter(config-if)# endRouter#Running Loopbacks
Use the loopback command to run a loopback tests.
loopback {diagnostic | payload | line}no loopback {diagnostic | payload | line}Where:
•
•
•
The following example shows how to run the diagnostic loopback:
Router(config)# interface atm 5/0/0Router(config-if)# loopback diagnosticATM PVC Commands
After you create a PVC using the pvc command, you can customize the PVC or a VC class by using the commands described in this section.
•
•
Specifying a Protocol
Use the protocol ip command in interface-ATM-VC configuration mode or VC-class configuration mode to configure a static map for an ATM PVC or VC class.
protocol ip {protocol-address | arp | cdp | clns | clns_es | clns_is | cmns | compressedtcp | {ip {address} | ppp | pppoe | snapshot}} [[no] broadcast]}no protocol ip {protocol-address | arp | cdp | clns | clns_es | clns_is | cmns | compressedtcp | {ip {address} | ppp | pppoe | snapshot}} [[no] broadcast]}Where:
•
•
•
•
•
•
•
•
•
•
•
•
•
For PVCs created under point-to-point subinterfaces, broadcast is enabled by default. For PVCs created under multipoint subinterfaces, use the broadcast argument to propagate IP routes.
Use the no form of this command to remove a static map.
Note
The following example shows how to specify IP protocol on an ATM PVC:
Router(config)# interface atm 5/0/0Router(config-if)# pvc 0/105Router(config-if-atm-vc)# protocol ip 172.16.32.49Configuring a Broadcast
Use the broadcast command to configure broadcast packet duplication and transmission for an ATM PVC or VC class.
The broadcast command is not used to enable ATM cell-level multicast, broadcast, replication, or to set up the broadcast of user level traffic. The broadcast command indicates which PVC (or PVCs) sends out broadcast traffic. This is typically limited to traffic associated with routing protocols and routing updates (for example, OSPF hello packets).
Note
Use the default form of this command to restore the default behavior described below.
broadcastno broadcastThe default is broadcast.
Use the no form of this command to disable transmission of broadcast packets.
For PVCs created under point-to-point subinterfaces, broadcast is enabled by default. For PVCs created under multipoint subinterfaces, you should use the broadcast command if you want to propagate IP routes (only the first PVC on a multipoint interface receives broadcast traffic).
The following example shows how to use the broadcast command to restore default behavior:
Router(config)# interface atm 5/0/0.4Router(config-subif)# pvc 0/105Router(config-if-atm-vc)# broadcastRouter(config-if-atm-vc)#Configuring Inverse ARP
Use the inarp command in interface-ATM-VC configuration mode or VC-class configuration mode to configure the inverse ARP time period for an ATM PVC or VC class.
inarp minutesno inarp minutesWhere minutes is the inverse ARP frequency from 1 to 60 minutes.
The default frequency is 15 minutes.Use the no form of this command to restore the default inverse ARP time period behavior.
Note
The following example shows how to specify an inverse ARP frequency of 40 minutes on an ATM PVC:
Router(config)# interface atm 5/0/0Router(config-if)# pvc 0/105Router(config-if-atm-vc)# inarp 40Attaching an ATM VC Class to a PVC
Use the class-vc command to attach an ATM VC class to a PVC.
class-vc nameWhere:
•
The following example shows how to assign an ATM VC class named boston to an ATM PVC:
Router(config)# interface atm 5/0/0.4Router(config-subif)# pvc 2/100Router(config-if-atm-vc)# class-vc bostonConfiguring VBR-NRT
Use the vbr-nrt command to configure the variable bit rate non real-time (VBR-NRT) traffic management type and specify output peak cell rate, output sustainable cell rate, and output maximum burst cell size for an ATM PVC or VC class.
You can use the vbr-nrt command in PVC configuration mode or VC-class configuration mode.
vbr-nrt peak_cell_rate sustainable_cell_rate maximum_burst_sizeno vbr-nrt peak_cell_rate sustainable_cell_rate maximum_burst_sizeWhere:
•
•
•
The default class of service is unspecified bit rate (UBR) running at the maximum line rate of the physical interface.
Use the no form of this command to remove the VBR-NRT parameters and return the PVC to its default of UBR.
The following example shows how to configure the VBR-NRT traffic parameters on an ATM PVC:
Router(config)# interface atm 5/0/0Router(config-if)# pvc 0/105Router(config-if-atm-vc)# vbr-nrt 10000 5000 200Specifying Encapsulation
Use the encapsulation command in PVC configuration mode or VC-class configuration mode to specify the ATM adaptation layer (AAL) and encapsulation type for an ATM PVC or VC class.
encapsulation {aal5mux ip | aal5snap}no encapsulation {aal5mux ip | aal5snap}Where:
•
•
Use the no form of this command to return an encapsulation to the default SNAP.
The following example shows how to specify aal5mux ip encapsulation for an ATM PVC:
Router(config)# interface atm 5/0/0.4Router(config-subif)# pvc 0/105Router(config-if-atm-vc)# encapsulation aal5mux ipEnabling ILMI Management
Use the ilmi manage command in PVC configuration mode or VC-class configuration mode to enable ILMI management on an ATM PVC. This command changes the convergence of higher-level protocols based on link-state changes.
ilmi manageno ilmi manageUse the no form of this command to disable ILMI management.The following example shows how to enable ILMI management on an ATM PVC:
Router(config)# interface atm 5/0/0Router(config-if)# pvc 0/105Router(config-if-atm-vc)# ilmi manageConfiguring OAM Retry
Use the oam retry command in PVC configuration mode or VC-class configuration mode to configure OAM retry.
oam retry up_value [down_value frequency]no oam retry up_value [down_value frequency]Where:
•
The default is 3 retries.
•
The default is 5 retries.
•
The default is 1 second.
Use the no form of this command to return OAM retry to its default values.
The following example shows how to configure OAM retry for an ATM PVC:
Router(config)# interface atm 5/0/0Router(config-if)# pvc 0/105Router(config-if-atm-vc)# oam retry 10 10 5Enabling OAM Loopback Cell Generation and Management
To enable end-to-end F5 OAM loopback cell generation and OAM management for an ATM PVC or VC class, use the oam-pvc command in PVC configuration mode or VC-class configuration mode.
oam-pvc [manage] [frequency]no oam-pvc [manage] [frequency]Where:
•
•
The default value is 10 seconds.
Use the no form of this command to disable generation of OAM loopback cells and OAM management.
The following example shows how to enable OAM loopback cell generation for an ATM PVC:
Router(config)# interface atm 5/0/0Router(config-if)# pvc 0/105Router(config-if-atm-vc)# oam-pvc 300Useful show Commands
You can use the following show commands to view ATM interfaces and subinterfaces, and to troubleshoot ATM problems.
