配置ISE 2.0 TrustSec SXP偵聽器和揚聲器
簡介
本文檔介紹如何配置思科身份服務引擎(ISE) 2.0版在偵聽器和揚聲器模式下支援TrustSec SGT交換協定(SXP)的功能並對其進行故障排除。
必要條件
需求
思科建議您瞭解以下主題：
- Cisco Catalyst交換機配置
- 身份服務引擎(ISE)和TrustSec服務
採用元件
本檔案中的資訊是根據以下軟體版本：
- Cisco Catalyst 3850交換機，帶軟體IOS-XE 3.7.2及更高版本
- Cisco ISE，版本2.0及更高版本
設定
網路圖表
流量傳輸
- 3850-2是10.0.0.100的802.1x身份驗證器- ISE返回安全組標籤(SGT) 16 (IT)以成功進行身份驗證
- 3850-2交換機學習請求方ip地址（ip裝置跟蹤）並使用SXP協定將對映資訊(IP-SGT)傳送到ISE
- 3850-1是10.0.0.1的802.1x身份驗證器- ISE返回SGT標籤9 （行銷）以成功進行身份驗證
- 3850-1從ISE接收SXP對映資訊（10.0.0.100是SGT 16），從ISE下載策略
- 從10.0.0.100傳送到10.0.0.1的流量由3850-2（未下載具體策略）轉發到3850-1，後者執行器將策略IT完成(16) ->市場行銷(9)
請注意，交換機之間的鏈路不是cts鏈路，因此交換機上的所有遠端對映都是透過SXP協定安裝的。
組態
有關基本TrustSec配置的詳細資訊，請參閱參考部分中的文章。
交換機3850-1
交換機透過SGT分配終止802.1x會話，並作為SXP揚聲器向ISE傳送。

ISE
步驟1.網路接入裝置
導航到工作中心>裝置管理>網路資源，使用共用金鑰cisco和TrustSec口令Krakow123增加兩台交換機。
步驟 2.安全性群組
要增加面向IT和市場行銷的SGT，請導航到工作中心> TrustSec >元件>安全組。
步驟3.安全組ACL
要增加安全組ACL，請導航到工作中心> TrustSec >元件>安全組ACL。
僅允許ICMP流量。
步驟 4.TrustSec策略
要增加控制從IT到行銷的資料流的策略，請導航到工作中心> TrustSec >元件>出口策略>矩陣。
設定預設條目catch all規則以拒絕所有流量。
步驟 5.SXP裝置
要為相應交換機配置SXP偵聽器和揚聲器，請導航到工作中心> TrustSec > SXP裝置。
使用口令cisco（或為交換機上的sxp配置的任何其它口令）。
步驟 6.授權策略
確保授權策略為每個使用者返回正確的SGT標籤，然後導航到策略>授權。
驗證
步驟 1.交換機加入CTS的ISE
從每台交換機提供TrustSec憑證（在ISE/Step1中配置）以獲取PAC。

從ISE對通向3850-1的流量進行資料包捕獲確認正在傳送SXP對映。
Wireshark使用標準SMPP解碼器。檢查負載：
「c0 a8 01 cb」(192.168.1.203)為10 (SGT = 16)
「0a 00 00 64」(10.0.0.100)為10 (SGT = 16)
3850-1安裝從ISE接收的所有對映。

步驟 5.策略下載和實施
從ISE下載正確的策略。（使用SGT 16的矩陣行）
KSEC-3850-1#show cts role-based permissions
IPv4 Role-based permissions default:
Permit IP-00
IPv4 Role-based permissions from group 16:SGT_IT to group 9:SGT_Marketing:
ICMP-10
Deny IP-00
RBACL Monitor All for Dynamic Policies : FALSE
RBACL Monitor All for Configured Policies : FALSE
允許從10.0.0.100 (SGT IT)到10.0.0.1 （SGT行銷）的ICMP流量，計數增加。
KSEC-3850-1#show cts role-based counters from 16
Role-based IPv4 counters
#Hardware counters are not available for specific SGT/DGT
#Use this command without arguments to see hardware counters
From To SW-Denied SW-Permitted
16 9 0 0 11 0
當嘗試使用telnet連線失敗時，丟棄計數器增加。
KSEC-3850-1#show cts role-based counters from 16
Role-based IPv4 counters
#Hardware counters are not available for specific SGT/DGT
#Use this command without arguments to see hardware counters
From To SW-Denied SW-Permitted
16 9 3 0 11 0
請注意，3850-2沒有特定策略，允許所有流量。
KSEC-3850-2#show cts role-based permissions
IPv4 Role-based permissions default:
Permit IP-00
RBACL Monitor All for Dynamic Policies : FALSE
RBACL Monitor All for Configured Policies : FALSE
在ISE上修改SG ACL後，在3850-1上增加permit tcp和cts刷新策略-然後接受telnet流量。
還可以使用Flexible Netflow（從IOS-XE 3.7.2開始為SGT感知）本地快取來確認行為。
flow record cts-v4
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match flow direction
match flow cts source group-tag
match flow cts destination group-tag
collect counter packets long
flow monitor F_MON
record cts-v4
interface GigabitEthernet1/0/3
ip flow monitor F_MON input
ip flow monitor F_MON output
結果顯示從3850-2接收的流量。源SGT為0，因為接收的資料流沒有任何SGT（無cts鏈路），但目標組標籤根據本地對映表自動替換。

Netflow本地快取可用於確認收到的流量。如果該流量被接受或丟棄，則由之前顯示的cts計數器確認。
ISE還允許生成SXP繫結和連線報告，如下圖所示。
