簡介
本文檔介紹如何使用vManage中可用的某些API呼叫,以及如何調整它以使用指令碼運行它。
問題
如果重疊包含數百或數千台思科邊緣路由器,則從vManage需要的資訊並不總是容易收集。
範例:
要獲取單個Cisco Edge路由器的運行配置,最簡單的方法是導航到Configuration > Devices > Wan Edge List,然後點選省略號(...)和Running Configuration。然後,您必須選擇並複製所有配置,然後將其儲存在另一個檔案中,如.txt格式。但是,如果您想獲得多個思科邊緣路由器的配置,則會出現問題,使得此任務非常耗時且非常耗時。


API呼叫概述
以下過程是一個示例,說明如何使用簡單的API呼叫獲取所需的所有資訊。
步驟 1.
使用URL或IP地址正常登入到vManage。

步驟 2.
開啟新的頁籤瀏覽器,然後複製並貼上vManage的URL,並新增字尾/apidocs(https://172.18.121.103:15256/apidocs)。

步驟 3.
在搜尋框中,鍵入Monitoring - Device Details。

步驟 4.
為了獲得一個裝置的配置,您必須嘗試/device/config API呼叫。

步驟 5.
輸入一個Cisco Edge路由器的System-IP,然後運行API呼叫。


在指令碼中使用Curl
更好的選擇是使用指令碼中的API呼叫生成Cisco Edge路由器的配置檔案。
步驟 1.
首先,在shell或CLI命令列中,建立儲存所有備份檔案的資料夾。
lufrias@LUFRIAS-M-P9Q2 Desktop % mkdir Backup_cedges
lufrias@LUFRIAS-M-P9Q2 Desktop % cd Backup_cedges
lufrias@LUFRIAS-M-P9Q2 Backup_cedges % pwd
/Users/lufrias/Desktop/Backup_cedges
lufrias@LUFRIAS-M-P9Q2 Backup_cedges %
步驟 2.
使用需要備份的思科邊緣路由器的所有系統IP地址建立一個.txt檔案。您可以從vManage和匯出CSV檔案獲得的系統IP地址清單。
需要將檔案命名為System-IPs.txt,並將其儲存在先前建立的同一目錄中(Backup_cedges)。


步驟 3.
確認檔案已儲存。
lufrias@LUFRIAS-M-P9Q2 Backup_cedges % ls -l
total 8
-rw-r--r--@ 1 lufrias staff 77 Aug 27 12:20 System-IPs.txt
lufrias@LUFRIAS-M-P9Q2 Backup_cedges %
步驟 4.
繼續建立指令碼。可以使用vi或任何記事本,但必須小心使用.sh格式儲存。
#!/bin/bash
#Define your variables
echo "Please type vManage URL in following format"
echo "https://172.18.121.103:15256 or https://vmanage.cisco.com"
read VMANAGE
echo "Please enter username to access vmanage"
read USER
echo "Password:"
read PASSWORD
#DEFINING THE API CALLS TO LOGIN AND BODY
security_url="$VMANAGE/j_security_check"
credentials="j_username=$USER&j_password=$PASSWORD"
#EXECUTE THE API CALL TO LOGIN TO THE VMANAGE.
curl --request POST --silent --insecure -c cookies.txt --url $security_url --data $credentials
#EXECUTE THE API CALL TO GET A TOKEN
TOKEN=$(curl "$VMANAGE/dataservice/client/token" -X GET -b cookies.txt -s --insecure)
arr_csv=()
while IFS= read -r line
do
arr_csv+=("$line")
curl --insecure -b cookies.txt -H "accept: text/plain" -H "X-XSRF-TOKEN: $TOKEN" -X GET "$VMANAGE/dataservice/device/config?deviceId="$line > $line.txt
echo $line
done < System-IPs.txt
echo "Running config was collected from following System_IPs:"
index=0
for record in "${arr_csv[@]}"
do
echo "Record at index-${index} : $record"
((index++))
done
curl "$VMANAGE/logout" -b cookies.txt --silent --insecure -H "X-XSRF-TOKEN: $TOKEN"
echo "Check files, if they are empty or with message "Bad request" check user and password"
步驟 5.
更改檔案的許可權,使其可以運行。

lufrias@LUFRIAS-M-P9Q2 Backup_cedges % chmod +x config_backup_script.sh

lufrias@LUFRIAS-M-P9Q2 Backup_cedges %
步驟 6.
使用/.config_backup_script.sh命令運行指令碼。請考慮完成此操作需要一些時間,具體取決於裝置的數量。
lufrias@LUFRIAS-M-P9Q2 Backup_cedges % ./config_backup_script.sh
