配置ISE 2.0 TrustSec SXP监听程序和扬声器
简介
本文描述如何配置和排除故障功能思科身份服务引擎(ISE)版本2.0支持TrustSec SGT交换协议(SXP)在制表人和扬声器模式。
先决条件
要求
Cisco 建议您了解以下主题：
- Cisco Catalyst交换机配置
- 身份服务引擎(ISE)和TrustSec服务
使用的组件
本文档中的信息基于以下软件版本：
- 思科有软件的IOS-XE 3.7.2 Catalyst 3850交换机及以后
- 思科ISE，版本2.0及以后
配置
网络图
通信流
- 3850-2是10.0.0.100的802.1x验证器-返回安全组标记(SGT) 16的ISE (IT)成功认证的
- 3850-2交换机学习请求方IP地址(跟踪的IP设备)并且发送映射信息(IP-SGT)使用SXP协议，对ISE
- 3850-1是10.0.0.1的802.1x验证器-返回成功认证的ISE SGT标记9 (营销)
- 3850-1获得从ISE的SXP映射信息(10.0.0.100是SGT 16)，下载从ISE的策略
- 从10.0.0.100发送的流量到10.0.0.1由3850-2转发(没有下载的特定策略)到是点击策略IT (16)的实施者的3850-1 - >营销(9)
请注意交换机之间的链路不是cts连接-，因此在交换机的所有远程映射通过SXP协议安装。
配置
关于关于基本TrustSec配置的详细信息，参考在References部分的条款。
交换机3850-1
交换机终止802.1x会话有SGT分配的并且作为往ISE的SXP扬声器。

步骤1.网络访问设备
导航对工作区>设备Administration >网络资源，添加两交换机用共享秘密cisco和TrustSec密码Krakow123。
步骤2.安全组
为了添加IT和营销的SGT，请导航对工作区> TrustSec >组件> Security组。
步骤3.安全组ACL
为了添加安全组ACL，请导航对工作区> TrustSec >组件> Security组ACL。
允许仅ICMP流量。
步骤4. TrustSec策略
为了从IT添加控制流量的策略到销售，请导航对工作区> TrustSec >组件>出口策略>矩阵。
设置DEFAULT条目抓住所有规则否决所有流量。
步骤5. SXP设备
为了配置SXP监听程序和扬声器对应的交换机的，请导航到工作区> TrustSec > SXP设备。
请使用密码cisco (或为在交换机的sxp配置的任何其他)。
步骤6.授权策略
保证授权策略回归更正每个用户的SGT标记，请导航对策略>授权。
验证
步骤1.加入cts的交换机ISE
从每交换机请提供TrustSec凭证(配置在ISE/Step1)获得PAC。

从流量的ISE采取的数据包捕获往3850-1确认SXP映射发送。
Wireshark用途标准的SMPP编码器。检查有效负载：

10 (SGT = 16) "0a的00 00 64" (10.0.0.100)
3850-1安装从ISE接收的所有映射。

步骤5.策略下载和实施
下载从ISE的正确策略。(与SGT 16)的矩阵行
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
从10.0.0.100 (SGT IT)的ICMP流量对10.0.0.1 (SGT营销)允许，计数器增加。
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 0 0 11 0
当尝试使用Telnet连接时出故障，丢弃计数器增加。
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

请注意没有在3850-2的特定策略，所有流量允许。
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的正在修改的SG ACL以后，添加permit tcp和cts刷新策略在3850-1 - Telnet流量然后接受。
其可能也使用灵活NetFlow (从IOS-XE 3.7.2开始它是意识的SGT)本地缓存确认行为。
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
结果显示从3850-2接收的流量。来源SGT是0，因为接收的流量没有任何SGT (没有cts链路)，但是目的地组标记自动地替换根据本地映射表。

Netflow本地缓存可以用于确认接收的流量。如果该流量接受或丢弃，那由以前被提交的cts计数器确认。
ISE也准许生成SXP绑定和连接报告，如此镜像所显示。
