目录


简介

当曾经LAN仿真(LANE)时,本文解释如何排除故障在Cisco设备的本地管理接口(ILMI)地址注册问题。

在访问ILMI管理信息库(MIB)的用户网络接口(UNI)间的ILMI协议用途简单网络管理协议(SNMP)格式数据包关联与在每个节点内的链路。ILMI协议通过允许邻接节点确定彼此的特性实现整个网络的自动配置。这些特性示例是大小彼此的连接空间,用于网络管理自动发现的(UNI或NNI),类型(公共或私有)和挂信令链路的种类。

ILMI也使用地址注册。

相关的错误消息

地址解析问题通常关联与以下错误消息:

%LANE-3-NOREGILMI: [chars] [chars] cannot register [ATM address] with ILMI

例如:

%LANE-3-NOREGILMI: ATM2/0/0.1 LEC cannot register 
47.00918100000000603E5A4501.00D0069A7C40.01 with ILMI

此错误消息可以由下列之一报告:

  • LAN仿真配置服务器(LECS)

  • LAN仿真服务器(LES)或广播及未知服务器(BUS)

  • LAN仿真客户端(LEC)

虽然本文查看LEC遇到的地址注册问题,说明为与LECS和LES/BUS的注册问题也是有效。

配置

网络图

此设置说明问题:

http://www.cisco.com/c/dam/en/us/support/docs/asynchronous-transfer-mode-atm/lan-emulation-lane/10450-ilmi-address-probs.gif

此设置使用:

  • Bernard是运行Cisco IOSï ¿  ½软件版本12.1(4)的Cisco 7500路由器。

  • 卡齐米是运行Cisco IOS软件版本12.0(13)W5(19b)的LightStream1010

  • Tintin是思科7000路由器运行Cisco IOS软件版本11.2(22)P。

此设置使用LANE,并且LECS和LES/BUS在LightStream1010查找。

注意: 使用的配置这里不提供最好的LANE性能;它使用为说明。对于关于LANE服务的设计建议,参考LANE设计推荐

检查 ILMI

ILMI 状态

检查的第一件事一旦地址注册问题通过ILMI是ILMI永久虚拟电路(PVC)是否是使用这些显示命令:

  • 在路由器上,请发出show atm vc命令

  • 在LightStream1010,请发出show atm vc interface atm x/y/z命令

bernard# show atm vc
            VCD /                                      Peak  Avg/Min Burst

ATM0/0/0          0    16    PVC    ATM2/0/0          0    35    ILMI   UP

!--- Output suppressed.

如果ILMI PVC是UP,则您必须检查哪ILMI状态路由器和ATM交换机在。通过发出show atm ilmi-status命令执行此。

bernard# show atm ilmi-status
 
Interface : ATM2/0/0 Interface Type : Private UNI (User-side) 
ILMI VCC : (0, 16) ILMI Keepalive : Disabled
ILMI State:       UpAndNormal

Peer MaxVPIbits:  8               Peer MaxVCIbits:  14
Active Prefix(s) :
47.0091.8100.0000.0060.3e5a.4501
Casimir# show atm ilmi-status atm 0/0/0

Interface : ATM0/0/0 Interface Type : Private UNI (Network-side) 
ILMI VCC : (0, 16) ILMI Keepalive : Enabled (5 Sec 4 Retries)
ILMI State:       UpAndNormal
Peer IP Addr:     15.1.1.1        Peer IF Name:     ATM2/0/0
Peer MaxVPIbits:  8               Peer MaxVCIbits:  16
Configured Prefix(s) :
47.0091.8100.0000.0060.3e5a.4501

正确状态是UpAndNormal。如果路由器或LightStream1010不在适当的ILMI状态,请检查是否有误配置使用给的说明以后在本文。

如果在交换机接口禁用 ILMI

您能证实或亦不ILMI是否在交换机接口禁用通过发出这些显示命令:

  • show run interface atm x/y/z

  • show atm ilmi-status atm z/y/z

Casimir# show run interface atm 0/0/0 
 Building configuration... 
 
Current configuration: 
   ! 

   interface ATM0/0/0 

    no ip address 
    no ip directed-broadcast 
    logging event subif-link-status 
    atm ilmi-keepalive 
    no atm ilmi-enable  

bernard# show atm ilmi-status atm 2/0/0
 
Interface : ATM2/0/0 Interface Type : Private UNI (User-side) 
ILMI VCC : (0, 16) ILMI Keepalive : Disabled
ILMI State:       UpAndNormal
Peer IP Addr:     0.0.0.0         
Peer MaxVPIbits:  8               Peer MaxVCIbits:  14 

bernard# show lane default-atm-addresses interface atm 2/0/0
LANE Client:        ...000000000002.**
LANE Server:        ...000000000003.**
LANE Bus:           ...000000000004.**
LANE Config Server: ...000000000005.00
note: ** is the subinterface number byte in hex

Casimir#

在这种情况下,作为ILMI在接口禁用通过发出no atm ilmi-enable命令,前缀没有发送到路由器并且,地址注册不能发生。

如只读或ILMI群配置的访问控制列表配置问题

如果在此安全报价的其中一应急方案adviory错误应用到LightStream1010或路由器,访问控制列表配置问题能发生。如果添加了这些线路到交换机配置,工作在交换机的ILMI (和PNNI)终止:

access-list deny any
snmp community ILMI view *ilmi RW

这有以下结果:

bernard# show atm ilmi-st
Interface : ATM2/0/0 Interface Type : Private UNI (User-side)    
ILMI VCC : (0, 16) ILMI Keepalive : Disabled 
ILMI State: WaitDevType

正如你看到的在路由器的Ilmi-status在WaitDevType坚持,并且地址注册不发生。

添加在路由器或交换机的以下配置在WaitDevType也将造成ILMI坚持和因而防止所有地址注册:

access-list <x> [permit|deny] a.b.c.d
snmp-server community ILMI RO <x>

如果路由器和交换机是在正确状态,则您必须证实信元是否在VC 0/16被发送并且接收。能执行此发出命令的您描述在本文的介绍。您在路由器能验证此通过发出这些显示命令:

  • show atm pvc 0/16

  • show atm vc vcd

在LightStream1010或Catalyst 8500 MSR上,请发出这些显示命令:

  • show atm vc interface atm x/y/z 0 16

  • show atm vc traffic interface atm x/y/z 0 16

bernard# show atm pvc 0/16

如果看到增加仅发送或的收到的计数,可以意味着信元在造成ILMI的背板被滞留被滞留。发出一shut/no shut命令在接口的尝试。如果那不帮助,与为做进一步的故障排除思科技术支持联系。如果两个计数器增加,则ILMI PVC适当地传送信元。

已知问题说明

也有能解释的一些已知bug ILMI为什么不适当地出现。这些是Cisco Bug ID CSCdt47492 (仅限注册用户), CSCdm26756 (仅限注册用户)和CSCdr28332 (仅限注册用户)。

其余本文假设, ILMI PVC上和运载信元,并且ILMI状态是正确在所有设备。然后,地址注册故障的可能的原因通过ILMI是:

  • 交换机已经认识NSAP地址

  • 配置问题

如果交换机知道 NSAP 地址

这些是交换机已经认识NSAP地址的方案。

如果在交换机上 静态配置 NSAP 地址

在路由器Bernard,您能看到此消息:

如上所述, NSAP地址在交换机和在这种情况下均等点静态配置对一个不同的接口从那个应该查找的地方。

如果另一个设备通过 ILMI 注册 NSAP 地址

要模拟此方案, TintinBernard配置与同一MAC地址。

Bernard
interface ATM2/0/0

 mac-address 0000.0000.0001
 pvc 0/16 ilmi
 !
 pvc 0/5 qsaal

Tintin
interface ATM1/0

 mac-address 0000.0000.0001
 no ip address
 atm pvc 1 0 5 qsaal
 atm pvc 2 0 16 ilmi

由于他们两个连接到同一交换机, NSAP地址关联对在sub-interface atm配置的LEC 2/0/0.1,并且atm 1/0.1是相同的:47.00918100000000603E5A4501.000000000001.01.

Tintin接口atm 1/0.1在Bernard的atm 2/0/0.1前启动。所以, Tintin是注册NSAP地址的第一个47.00918100000000603E5A4501.000000000001.01通过ILMI。当接口atm 2/0/0.1在Bernard启动,此消息显示:

1w1d: %LANE-3-NOREGILMI: ATM2/0/0.1 LEC cannot register 
47.00918100000000603E5A4501.000000000001.01 with ILMI

如果查看Tintin,您能看到Tintin在卡齐米已经使用该NSAP地址和注册它:

这意味着Bernard不能通过ILMI注册其地址,因为它是重复项。当debug atm ilmi atm x/y/z命令在Bernard和卡齐米时发出,这些调试能被看到:

注意: 在此部分描述的情况在下列场景可能经常被遇到。如果LECS服务在Cisco设备配置,并且其他厂商的设备同时和所有这些LECS侦听对众所周知的地址并且通告它,此消息可以显示:

当LECS在非Cisco设备以及Cisco设备配置,您不能使用Fast-SSRP SSRP。这些冗余协议目的是一个LECS选择作为万事达LECS (是的其他备用LECS)。如果使用,主控LECS是允许的只那个通告众所周知的地址。在这种情况下,因为您不能配置冗余协议,没有万事达LECS选择。因此,所有LECS设法通告众所周知的地址,但是仅一个成功。

要说明此,配置被修改了如显示:

使用此新建的配置, LECS在Bernard和卡齐米配置,并且LECS地址数据库在卡齐米未配置。这意味着SSRP没有启用。要说明错误消息, Bernard ATM 2/0/0接口被关闭,在配置前,并且首先修改卡齐米配置。在这种情况下,卡齐米通过ILMI通告众所周知的地址,因而防止Bernard如此执行。当Bernard ATM 2/0/0接口启动,此消息显示:

1w2d: %LANE-3-NOREGILMI: ATM2/0/0 LECS cannot register 
47.007900000000000000000000.00A03E000001.00 with ILMI

配置问题

地址注册的失败的另一个可能的原因是与配置的一问题在LightStream1010。

interface ATM0/0/0 

 no ip address 

 no ip directed-broadcast 

 logging event subif-link-status 

 atm ilmi-keepalive 

 no atm address-registration

以上的命令通过ILMI防止,在这种情况下,防止路由器接收其前缀和也因而通告其对交换机的地址的所有地址注册:

bernard# show lane default-atm-addresses interface atm 2/0/0
LANE Client:        ...000000000002.**
LANE Server:        ...000000000003.**
LANE Bus:           ...000000000004.**
LANE Config Server: ...000000000005.00
note: ** is the subinterface number byte in hex
 
bernard# show atm ilmi-status atm 2/0/0
 
Interface : ATM2/0/0 Interface Type : Private UNI (User-side) 
ILMI VCC : (0, 16) ILMI Keepalive : Disabled
ILMI State:       UpAndNormal
Peer IP Addr:     10.200.10.12    Peer IF Name:     ATM0/0/0
Peer MaxVPIbits:  8               Peer MaxVCIbits:  14

路由器不接收其前缀并且地址注册不能发生。

当启用在LightStream1010时的debug atm ilmi atm0/0/0,这能被看到,当atm0/0/0接口启动时:


!--- Output suppressed.
 
Apr  2 12:42:11.792: ILMI: My Device  type is set to Node (ATM0/0/0)
Apr  2 12:42:11.792: ILMI(ATM0/0/0): From  NodeConfigComplete To  UpAndNormal  <ilmi_process_intfRestart>
Apr  2 12:42:11.792: ILMI(ATM0/0/0): Keep Alive enabled
Apr  2 12:42:11.792: ILMI(ATM0/0/0) Address Registration disabled. Prefix not sent 

!--- Output suppressed.

解决方案将重新启用atm address-registration和执行在ATM接口的shut/no shut重新启动ILMI。
