本文檔介紹使用/不使用硬體USB電子令牌時Cisco Unified Communications Manager (CUCM)安全性的區別。
思科建議您瞭解CUCM版本10.0(1)或更高版本。此外,請確保:
有關詳細資訊,請參閱Cisco Prime License Manager版本11.5(1)SU2發行版本註釋。
為了更清楚瞭解,此要求僅在您在任何時候都有需要USB eToken的場景時才適用。大多數人都需要USB電子令牌的可能性很小。
注意:預設情況下,Cisco Jabber和許多Cisco TelePresence或Cisco 7940/7960系列IP電話當前不支援安全功能。如果您在預設情況下不支援安全性的裝置上部署無令牌CTL,則對您的系統進行任何更改發佈伺服器上的CallManager證書的更新都會阻止這些裝置的正常功能,直到手動刪除CTL。預設情況下,支援Security的裝置(例如7945和7965或更新的電話)在發佈伺服器上的CallManager證書更新時能夠安裝CTL檔案,因為它們可以使用信任驗證服務(TVS)。
本文中的資訊係根據以下軟體和硬體版本:
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。
本文檔介紹使用和不使用硬體USB電子令牌時Cisco Unified Communications Manager (CUCM)安全性的區別。
本檔案也說明涉及無標籤憑證信任清單(CTL)的基本實行案例,以及用來確保系統在變更後可正常運作的程式。
無令牌CTL是CUCM版本10.0(1)及更高版本中的一項新功能,允許對IP電話的呼叫信令和媒體進行加密,而無需使用硬體USB電子令牌和CTL客戶端外掛,這是早期CUCM版本中的要求。
當使用CLI命令將群集置於混合模式時,CTL檔案使用發佈伺服器節點的CCM+TFTP(伺服器)證書進行簽名,並且CTL檔案中沒有eToken證書。
注意:當您在發布者上重新生成CallManager (CCM+TFTP)證書時,它將更改檔案的簽名者。預設情況下,不支援安全性的電話和裝置也不接受新的CTL檔案,除非從每個裝置手動刪除CTL檔案。有關詳細資訊,請參閱本文檔的「要求」部分列出的最後一項要求。
本節介紹透過CLI將CUCM集群安全移至混合模式的過程。
在此場景之前,CUCM處於非安全模式,這意味著任何節點上都不存在CTL檔案,並且註冊的IP電話僅安裝身份信任清單(ITL)檔案,如以下輸出所示:
admin:show ctl Length of CTL file: 0 CTL File not found. Please run CTLClient plugin or run the CLI - utils ctl.. to
generate the CTL file. Error parsing the CTL File. admin:
注意:如果叢集不是處於混合模式時,在伺服器上找到CTL檔案,這表示叢集曾經處於混合模式,然後移回非混合模式,而且CTL檔案並未從叢集中刪除。
命令檔案delete activelog cm/tftpdata/CTLFile.tlv從CUCM集群的節點中刪除CTL檔案;但是,需要在每個節點上輸入該命令。要明確的是,僅當伺服器具有CTL檔案且群集未處於混合模式時,才使用此命令。
確認集群是否處於混合模式的一個簡單方法是使用run sql select paramname,paramvalue from processconfig where paramname='ClusterSecurityMode'命令。如果引數值為0,則叢集不處於混合模式。
run sql select paramname,paramvalue from processconfig where paramname='ClusterSecurityMode' paramname paramvalue =================== ========== ClusterSecurityMode 0
要透過使用新的無令牌CTL功能將CUCM集群安全移至混合模式,請完成以下步驟:
admin:utils ctl set-cluster mixed-mode
This operation sets the cluster to Mixed mode. Do you want to continue? (y/n):y
Moving Cluster to Mixed Mode
Cluster set to Mixed Mode
Please Restart the TFTP and Cisco CallManager services on all nodes in the cluster

注意:在輸出中,如果CUCM發佈伺服器的CCM+TFTP(伺服器)證書未簽名,請返回基於硬體電子令牌的集群安全模式,然後重新更改無令牌解決方案。
本節介紹如何將CUCM集群安全從新的無令牌解決方案遷移回使用硬體電子令牌。
如果使用CLI命令將CUCM集群安全設定為混合模式,並且CTL檔案使用CUCM Publisher節點的CCM+TFTP(伺服器)證書進行簽名,則CTL檔案中不存在來自硬體USB電子令牌的證書。
因此,當您運行CTL客戶端以更新CTL檔案(返回使用硬體電子令牌)時,將顯示以下錯誤消息:
The Security Token you have inserted does not exist in the CTL File Please remove any Security Tokens already inserted and insert another
Security Token. Click Ok when done.
在包括將系統降級到不包括utils ctl 命令的10.x之前版本的情況下(當切換回版本時),這一點尤為重要。
之前的CTL檔案在刷新或Linux到Linux (L2)升級過程中被遷移(其內容沒有更改),並且它不包含eToken證書,如前所述。以下是輸出示例:

本節介紹在使用無令牌CTL解決方案時如何重新生成CUCM集群安全證書。
在CUCM維護過程中,有時會更改CUCM發佈伺服器節點CallManager證書。
發生這種情況的情況包括更改主機名、更改域或僅僅重新生成證書(由於關閉證書過期日期)。
更新CTL檔案後,使用與IP電話上安裝的CTL檔案中存在的證書不同的證書對其進行簽名。
通常,這個新的CTL檔案不被接受;但是,當IP電話找到用於簽署CTL檔案的未知證書後,它會聯絡CUCM上的TVS服務。
註:TVS伺服器清單位於IP電話配置檔案中,並且從IP電話裝置池> CallManager組對映到CUCM伺服器。
成功驗證TVS伺服器後,IP電話會使用新版本更新其CTL檔案。這種情況下會發生以下事件:
