驗證路由PON部署24.1.2

簡介

本檔案介紹在虛擬機器器(VM)和XR路由器上驗證Cisco路由PON （被動光纖網路）解決方案。

必要條件

需求

思科建議瞭解以下主題。

• Cisco IOS® XR軟體
• Linux
• 虛擬機器器環境

採用元件

本檔案中的資訊是根據列出的軟體和硬體版本：

• NCS-540-28Z4C-SYS-A XR路由器
• 思科IOS® XR軟體24.1.2
• 路由PON版本24.1.2
• Ubuntu版本20.04.06 LTS

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。

驗證步驟- XR路由器

組態檢查

Linux網路

確保用於連線的VRF（虛擬路由和轉發）反映在linux網路配置中。在本示例中，已配置VRF Mgmt-intf。此外，請確保為正確的上行鏈路介面設定了source-hint default-route。所列示例中的連線使用介面MgmtEth0/RP0/CPU0/0。

組態範例:

linux networking
 vrf Mgmt-intf
  address-family ipv4
   default-route software-forwarding
    source-hint default-route interface MgmtEth0/RP0/CPU0/0

物理介面和子介面配置

確保插入OLT（光線路終端）插頭的介面正確且配置中並未關閉。此外，確認子介面使用dot1q標籤4090並應用於關聯的物理介面。

組態範例:

interface TenGigE0/0/0/0
description PON OLT
!
interface TenGigE0/0/0/0.4090
encapsulation dot1q 4090

命令驗證：

Encapsulation 802.1Q Virtual LAN, VLAN Id 4090, loopback not set

確保在全局配置中啟用LLDP。

PON控制器配置

確保已安裝xr-pon-ctrl RPM且處於活動狀態。如果不是，請確認NCS540l-iosxr-optional-RPMs-24.2.11.tar存在於硬碟上（在Linux shell中，路徑為/misc/disk1/），並且正確引用包含匹配RPM的軟體的local-repo。

範例：

RP/0/RP0/CPU0:F340.16.19.N540-2#show install active summary | include xr-pon
Tue Jul 16 14:59:16.082 UTC
xr-pon-ctlr 24.1.2v1.0.0-1

install
 repository local-repo
  url file:///harddisk:/optional-RPMs-2412

確保PON控制器配置了正確關聯的檔案、檔案路徑和VRF。

範例：

pon-ctlr
 cfg-file harddisk:/PonCntlInit.json vrf Mgmt-intf

驗證

JSON檔案

確保host：部分設定了MongoDB的IP，以便與PON控制器所連線的裝置匹配。此外，確認配置的埠與VM中mongod.conf檔案的埠匹配。

範例：

   "CNTL": {
       "Auth": false,
       "CFG Version": "R4.0.0",

   },
   "databaseType": "MongoDB",

}

連線檢查

從XR路由器，對MongoDB/VM託管路由PON管理器執行ping操作。如果您使用的是VRF，請從VRF獲取源。

範例：

RP/0/RP0/CPU0:F340.16.19.N540-1#ping vrf Mgmt-intf 10.122.140.232
Tue Jul 16 15:09:52.780 UTC
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.122.140.232 timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/3 ms
RP/0/RP0/CPU0:F340.16.19.N540-1#

容器狀態

PON控制器在XR路由器的塢站容器上運行。透過登入到XR路由器中的linux shell來檢查容器的狀態，然後運行命令docker ps。這會顯示目前使用中的容器（若有的話）。

範例：

RP/0/RP0/CPU0:F340.16.19.N540-1#run
Tue Jul 16 15:14:26.059 UTC
[node0_RP0_CPU0:~]$docker ps
CONTAINER ID   IMAGE                   COMMAND                CREATED    STATUS PORTS   NAMES
2e700f202ee3   tibit-poncntl.xr:R4.0.0 "/usr/bin/supervisor…" 3 days ago Up     3 days  pon_ctlr

如果docker容器未運行，請檢查JSON檔案的內容和檔案結構。檢查docker容器的日誌中是否有任何活動錯誤。日誌示例顯示一個ONU向控制器註冊。這也會列印容器與OLT相關的任何檔案層級錯誤。此外，可以透過運行簡單的show logging來檢查錯誤消息來獲得指導。

範例：

[node0_RP0_CPU0:~]$docker logs pon_ctlr

2024-07-16 15:05:11.630 PonCntl System Status
{
"e0:9b:27:36:aa:76": {
"OLT State": "Primary",
"ONU Active Count": 1,
"ONUs": {
"CIGG2410503f": "Registered"

日期和時間

確保XR路由器和託管路由PON管理器的VM上的時間和日期匹配。如果可能，請使用相同的NTP伺服器以獲得最佳準確性。

範例：

RP/0/RP0/CPU0:F340.16.19.N540-1#show clock
Tue Jul 16 15:25:03.781 UTC
15:25:03.827 UTC Tue Jul 16 2024

組態範例:

ntp
 server vrf Mgmt-intf 172.18.108.14 source MgmtEth0/RP0/CPU0/0
 server vrf Mgmt-intf 172.18.108.15 prefer source MgmtEth0/RP0/CPU0/0

追蹤訊息

PON進程透過ltrace生成附加的日誌記錄。檢查這些日誌，查詢與此進程相關的任何錯誤。

範例：

RP/0/RP0/CPU0:F340.16.19.N540-1#show pon-ctlr ltrace all reverse location all
Wed Jul 17 13:25:43.747 UTC

驗證步驟- Linux VM

驗證

status.sh命令檔

在Routed PON Manager安裝目錄中，有一個shell指令碼(status.sh)顯示每個關聯進程的當前狀態。以提升的許可權執行此命令檔，以確認列出的各項服務都已啟動並執行。如果其中一個服務未執行，請先檢查執行安裝時執行的安裝指令碼，並確保根據安裝指南設定適當的引數。

Netplan

驗證Netplan並確保IP資訊有效、VM網路介面名稱正確、建立和分配了VLAN id 4090，並且它使用有效的Netplan YAML樹結構。

範例：

rpon@rpon-mgr:~/PON_MANAGER_SIGNED_CCO/R4.0.0-Cisco-UB2004-sign/R4.0.0-Cisco-UB2004$ cat /etc/netplan/01-network-manager-all.yaml 
network:
  version: 2
  Renderer: Network Manager
  ethernets:
    ens192: <- VM Network Adapter
      dhcp4: no <- No DHCP as the IP is set statically
      dhcp6: no
      addresses: [10.122.140.232/28] <- IP of the VM Network adapter
      gateway4: 10.122.140.225 <- GW of the IP Network
      nameservers:
        addresses: [172.18.108.43,172.18.108.34] <- Network DNS
  vlans:
    vlan.4090:
      id: 4090
      link: ens192 <- VM Network adapter
      dhcp4: no
      dhcp6: no 

驗證VM的IP配置，以及配置的網路介面卡是否與netplan YAML檔案中列出的相匹配。

範例：

rpon@rpon-mgr:~$ ifconfig
ens192: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
        inet 10.122.140.232 netmask 255.255.255.240 broadcast 10.122.140.239

IP連線能力

透過ping驗證與託管PON控制器的XR路由器的IP連線。

範例：

rpon@rpon-mgr:~/PON_MANAGER_SIGNED_CCO/R4.0.0-Cisco-UB2004-sign/R4.0.0-Cisco-UB2004$ ping 10.122.140.226

rtt min/avg/max/mdev = 1.009/1.054/1.128/0.052 ms

驗證MongoDB TCP埠27017是否已打開。如果為MongoDB使用非標準埠，請透過netstat -tunl驗證該埠是否打開/偵聽。

範例：

rpon@rpon-mgr:~/PON_MANAGER_SIGNED_CCO/R4.0.0-Cisco-UB2004-sign/R4.0.0-Cisco-UB2004$ netstat -tunl
Active Internet connections (only servers)

MongoDB配置檔案

驗證mongod.conf檔案是否準確，以及bindIP：下是否具有正確的IP。

範例：

rpon@rpon-mgr:~/PON_MANAGER_SIGNED_CCO/R4.0.0-Cisco-UB2004-sign/R4.0.0-Cisco-UB2004$ cat /etc/mongod.conf 
# mongod.conf
