802.1x DACL、每用户ACL、过滤器ID和设备跟踪的行为
目录
简介
本文如何描述IP设备跟踪功能工作，包括什么触发是添加并且删除主机。并且，跟踪设备的影响在可下载的802.1x访问控制表(DACL)解释。行为更改在版本和平台之间。
本文的第二部分着重访问控制表(ACL)返回由验证、授权和统计(AAA)服务器和应用对802.1x会话。提交在DACL、每用户ACL和过滤器ID ACL之间的一个比较。并且，关于ACL重写的一些警告和默认ACL讨论。
设备跟踪的理论
设备跟踪添加一个条目，当：
- 它通过监听的DHCP了解新的条目。
- 它通过地址解析协议(ARP)请求了解新的条目(读发送方MAC地址和发送方IP地址从ARP数据包)。功能有时呼叫ARP检查，但是它不是相同的象动态ARP检查(戴)。默认情况下功能启用并且不可能禁用。它也呼叫监听的ARP，但是调试不会显示它，在“监听的debug arp”启用后。监听默认情况下的ARP启用并且不可能禁用或被控制。
设备跟踪删除条目，当没有ARP请求的时无响应(发送每台主机的探测器在跟踪表，默认情况下每30秒)的设备。

有问题，当您有一ARP响应时，但是跟踪条目的设备无论如何删除。bug在版本12.2.55或15.x软件方面看来在版本12.2.33和没出现。
并且有一些差异，当处理用L2端口(access-port)时和L3端口(没有switchport)。

跟踪为版本12.2.55的IP设备-隐藏命令
对于版本12.2也许有需要使用隐藏命令为了激活它：

跟踪为版本12.2.55的IP设备-静态IP示例
在本例中， PC配置与静态IP地址。调试显示，在您得到ARP响应(MSG=2)后，跟踪条目的设备更新。
01:03:16: sw_host_track-ev:0050.5699.4ea1 Stopping cache timer
01:03:16: sw_host_track-ev:0050.5699.4ea1: Send Host probe (0)

01:03:16: sw_host_track-ev:0050.5699.4ea1 Starting cache timer: 30 seconds
那么从PC的每个ARP请求更新跟踪表的设备(发送方MAC地址和发送方IP地址从ARP数据包)。
跟踪为版本15.x的IP设备
请记住例如802.1x的DACL LAN轻版本不支持某些功能(请当心- Cisco Feature Navigator总是不显示正确信息)。
从版本12.2的隐藏命令可以被执行，但是不会有效果。在软件版本15.x中，跟踪的IP设备(IPDT)默认情况下为有启用的802.1x的接口只启用：
bsns-3750-5#show ip device tracking all

在802.1x配置以后删除从端口， IPDT从该端口也将删除。端口状态也许是“DOWN”，因此有“switchport mode access”和“authenticaion波尔特控制自动”为了有在该端口激活的IP设备跟踪是必要的。最大接口设备限制定到10 ：
bsns-3750-5(config-if)#ip device tracking maximum ?
<1-10> Maximum devices
跟踪为Cisco IOS XE ®的IP设备
再次，在Cisco IOS XE 3.3的行为更改，当与Cisco IOS版本15.x比较。从版本12.2的隐藏命令过时，但是此错误当前将返回：
3850-1# no ip device tracking int g1/0/48

在Cisco IOS XE，设备跟踪为所有接口(没有配置的802.1x)的那些激活：

那么IP地址然后没有附加，但是DACL仍然应用：

Extended IP access list xACSACLx-IP-DACL-516c2694 (per-user)

在此方案中，跟踪为802.1x的设备没有要求。唯一的差异是那认识客户端的IP地址可以在前面用于RADIUS访问请求。在属性8以后附加：
radius-server attribute 8 include-in-access-req
它在Access-Request将存在，并且在ACS创建更加粒状的授权规则将是可能的：
00:17:44: RADIUS(00000001): Send Access-Request to 10.48.66.185:1645 id 1645/27, len 257

记住TrustSec也需要跟踪为IP的IP设备对SGT捆绑。
跟踪与802.1x和DACL的IP设备版本15.x的
版本15.x和版本12.2.55有何区别在DACL ？在软件Version15.x方面，它为验证代理工作同一样。通用的ACL能被看到，当show ip access-list命令被输入(从AAA的被缓存的答复)时，但是，在显示IP访问控制列表接口fa0/1命令， src “其中任一”由主机的源IP地址后替换(已知通过跟踪的IP设备)。
这是电话和PC的示例在一个端口(g1/0/1)，在3750X的软件版本15.0.2SE2 ：

而PC使用dot1x，电话通过MAC验证旁路(MAB)验证。电话和PC使用同样ACL ：
bsns-3750-5#show ip access-lists xACSACLx-IP-PERMIT_ALL_TRAFFIC-51134bb2
Extended IP access list xACSACLx-IP-PERMIT_ALL_TRAFFIC-51134bb2 (per-user)
10 permit ip any any
然而，当验证在接口级上来源由设备的IP地址替换了。IP设备跟踪更改的触发的和它能在任何时间发生(以后比ACL的验证会话和下载) ：
bsns-3750-5#show ip access-lists interface g1/0/1
permit ip host 192.168.2.200 any (5 matches)
permit ip host 192.168.10.12 any
应该标记两MAC地址作为静态：
bsns-3750-5#sh mac address-table interface g1/0/1

---- ----------- -------- -----
20 0050.5699.4ea1 STATIC Gi1/0/1
100 0007.5032.6941 STATIC Gi1/0/1
特定ACL条目
来源“其中任一”在DACL什么时候用主机IP地址替换？只有当有相同端口的(两名恳求者)至少两会话。
当只有一会话时，没有需要替换来源“其中任一”。问题也许出现，当有多个会话时，并且对于不是所有IP设备跟踪认识主机的IP地址。在该方案中它将是“中的任一”为一些条目。
该行为是不同的在一些平台。例如，既使当有每个端口，一验证会话在与版本15.0(2)EX的2960X ACL永远特定。然而，对于3560X和3750X版本15.0(2)SE，您需要有做至少两的会话该ACL特定。
控制方向
默认情况下，控制方向是类型两个：
bsns-3750-5(config)#int g1/0/1
bsns-3750-5(config-if)#authentication control-direction ?
both Control traffic in BOTH directions
in Control inbound traffic only
bsns-3750-5(config-if)#authentication control-direction both
那意味着，在请求方验证前，流量不可能发送到/从端口。为“在”模式，流量可能发送从端口到请求方，但是不从请求方到端口(可能是有用的为在LAN功能的苏醒)。
但是，交换机应用ACL在“在”方向。不重要使用哪个模式。
bsns-3750-5#sh ip access-lists interface g1/0/1 out
bsns-3750-5#sh ip access-lists interface g1/0/1 in
permit ip host 192.168.2.200 any
permit ip host 192.168.10.12 any
那基本意味，在验证ACL为对端口的流量应用(方向的)后，并且所有流量从端口(方向)允许。
跟踪与802.1x和每用户ACL的IP设备版本15.x的
使用每用户ACL在cisco-av-pair “ip通过的也是可能的：inacl”并且“ip ：outacl”。
此配置示例类似于先前配置，但是这次电话使用DACL和PC用途每用户ACL。PC的ISE配置文件是：
电话仍然有DACL应用：
bsns-3750-5#show authentication sessions interface g1/0/1

然而，在相同端口的PC使用每用户ACL ：

为了验证那如何在gig1/0/1端口合并：
bsns-3750-5#show ip access-lists interface g1/0/1
permit icmp host 192.168.2.200 any log
permit ip host 192.168.10.12 any
首先进入从每用户ACL被采取了(注意日志关键字)，并且第二个条目从DACL被采取。他们两个由跟踪为特定IP地址的IP设备重写。
每用户ACL能验证与all命令调试的epm ：
Apr 12 02:30:13.489: EPM_SESS_EVENT:IP Per-User ACE: permit icmp any any log received

bsns-3750-5#show ip access-lists

10 permit icmp any any log
怎么样ip ：outacl属性？它完全在版本15.x省略。属性接收，但是交换机不应用/加于的进程。
差异，当与DACL比较
在Cisco Bug ID CSCut25702中注明，每用户ACL跟DACL不同运行。与一个条目(“permit ip any any”)和一请求方的DACL连接对端口能正确地运作，无需IP设备跟踪启用。“任何”参数不会被替代，并且所有流量将允许。然而，为了每用户ACL是必须安排IP设备跟踪启用。如果它禁用并且有“permit ip any any”条目和一请求方，则所有流量将阻塞。
跟踪与802.1x和过滤器ID ACL的IP设备版本15.x的
并且，可以使用IETF属性过滤器ID [11]。AAA服务器返回ACL名称，在交换机应该定义本地。 ISE配置文件能如下所示:
注意您需要specifiy方向(在或)。对于那它手工是必要的添加属性：
然后调试显示：
debug epm all
Apr 12 23:41:05.170: EPM_SESS_EVENT:Filter-Id : Filter-ACL received

并且，作为ACL是已绑定的对接口：
bsns-3750-5#show ip access-lists interface g1/0/1
permit icmp host 192.168.2.200 any log
permit tcp host 192.168.2.200 any log
注意此ACL可以与ACL的其他类型在同一个接口的合并。例如，有在从ISE获得DACL的同一交换机端口另一请求方： “permit ip any any”您可能发现：
bsns-3750-5#show ip access-lists interface g1/0/1
permit icmp host 192.168.2.200 any log
permit tcp host 192.168.2.200 any log
permit ip host 192.168.10.12 any
注意IP设备跟踪重写每来源的(请求方)来源IP。
怎么样“”过滤器列表？再次(作为每用户ACL)，它不会由交换机使用。
IP设备跟踪-默认和最佳实践
对于版本早于15.2(1)E，在所有功能能使用IPDT它前需要用此CLI命令全局首先启用：
(config)#ip device tracking
对于版本15.2(1)E和以后， IP设备trace命令没有必要。IPDT启用，只有当依靠它的功能启用它。如果功能不启用IPDT， IPDT禁用。跟踪”命令的“IP设备没有效果。特定功能有启用/禁用的控制IPDT。
当您启用IPDT时，您必须记住关于" Duplicate IP Address "问题。欲知更多信息，请参阅排除故障“重复IP地址0.0.0.0”错误消息。
推荐禁用在中继端口的IPDT ：
(config-if)# no ip device tracking
在最新Cisco IOS，它是不同命令：
(config-if)# ip device tracking maximum 0
推荐使在接入端口和延迟ARP探测器的IPDT为了避免" Duplicate IP Address "问题：
(config-if)# ip device tracking probe delay 10
接口版本15.x的ACL重写
对于接口ACL，它在验证前工作：
interface GigabitEthernet1/0/2
description windows7
switchport mode access
ip access-group test1 in
authentication order mab dot1x
authentication port-control auto
mab
dot1x pae authenticator
end
bsns-3750-5#show ip access-lists test1
Extended IP access list test1
10 permit tcp any any log-input
然而，在验证成功后它由从AAA服务器返回的ACL重写(覆盖) (不重要，如果它是DACL， ip ：inacl或者filterid)。
该ACL (test1)能阻塞在Open模式通常将允许)的流量(，但是，在验证不再后重要。既使当ACL没有从AAA服务器返回，接口ACL覆盖，并且提供完全权限。那有点误导，因为三重内容可编址存储器表明ACL仍然是在接口级上的已绑定的。这是从版本15.2.2的一示例在3750X ：
bsns-3750-6#show platform acl portlabels interface g1/0/2
Port based ACL: (asic 1)
----------------------------
Input Label: 5 Op Select Index: 255
Interface(s): Gi1/0/2
Access Group: test1, 4 VMRs
Ip Portal: 0 VMRs
IP Source Guard: 0 VMRs
LPIP: 0 VMRs
AUTH: 0 VMRs
C3PLACL: 0 VMRs
MAC Access Group: (none), 0 VMRs
该信息是仅有效为接口级，不为会话级别。有些信息(提交被配制的ACL)可以推导从：
bsns-3750-6#show ip access-lists interface g1/0/2
permit ip host 192.168.1.203 any
Extended IP access list test1
10 permit icmp host 2.2.2.2 host 1.1.1.1
首先进入创建作为“permit ip any any” DACL为成功认证返回(和“其中任一”由从跟踪表)的设备的一个条目替换。第二个条目是接口ACL的结果和为所有应用新建的认证(在授权前)。
不幸地， (再从属的平台)两个ACL被连接。那在3750X的版本15.2.2发生。那意味着为已授权会话，他们两个应用。首先DACL和第二接口ACL。所以，当您添加明确“deny ip any any”， DACL不会考虑到接口ACL。通常明确拒绝在DACL接口ACL以后然后应用那。
版本15.0.2的行为在3750X是相同的，但是interface命令嘘的IP访问控制列表不再显示接口ACL (但是它用接口ACL在DACL将连接，除非明确拒绝存在)。
用于802.1x的默认ACL
有默认ACL的两种类型：
- 验证默认ACL开放-使用Open模式
- 用于已关闭访问-的验证默认ACL
验证默认ACL和验证默认ACL开放，当端口在未授权的状态时，使用。 默认情况下，使用关闭的访问。那意味着，在验证所有流量丢弃前，除了那个由验证默认ACL允许。此方式DHCP流量在成功的授权前允许。分配IP地址，并且下载的DACL可以正确地应用。ACL自动地创建并且不可能在配置找到。
bsns-3750-5#sh run | i Auth-Default
bsns-3750-5#sh ip access-lists Auth-Default-ACL
Extended IP access list Auth-Default-ACL
10 permit udp any range bootps 65347 any range bootpc 65348 (22 matches)
20 permit udp any any range bootps 65347 (12 matches)
30 deny ip any any
它为第一验证动态地创建(在认证和授权相位之间)并且删除，在最后会话删除后。
验证默认ACL允许仅DHCP流量。在验证成功后，并且新的DACL下载，应用给该会话。当模式更改打开验证默认ACL开放出现，并且时相似地使用并且工作作为验证默认ACL ：
bsns-3750-5(config)#int g1/0/2
bsns-3750-5(config-if)#authentication open
bsns-3750-5#show ip access-lists
Extended IP access list Auth-Default-ACL-OPEN
10 permit ip any any
两个ACL可以定制，但是他们在配置里不会被看到。
bsns-3750-5(config)#ip access-list extended Auth-Default-ACL
bsns-3750-5(config-ext-nacl)#permit udp any any
bsns-3750-5#sh ip access-lists
Extended IP access list Auth-Default-ACL
10 permit udp any range bootps 65347 any range bootpc 65348 (22 matches)
20 permit udp any any range bootps 65347 (16 matches)
30 deny ip any any
40 permit udp any any
bsns-3750-5#sh run | i Auth-Def
bsns-3750-5#
Open模式
前面部分描述默认情况下(行为包括Open模式使用的那个)的ACL的。Open模式的行为是：
- 它允许所有流量(根据验证默认ACL开放的默认)，当会话在一未授权的状态时。
- 会话在一未授权的状态在认证/授权时(有益于加密设备型号E (PXE)引导程序方案)或该进程以后发生故障(有益于方案呼叫“低影响模式”)。
- 当会话移动向多个平台的时Authorized State， ACL被连接，并且使用第一个DACL，然后接口ACL。
- 对于多验证或多域也许同时有多个会话用不同的状态(另外ACL类型然后将申请每会话)。
当接口ACL是必须
对于多个6500/4500平台，接口ACL是必须为了正确地应用DACL。
这是与4500个sup2 12.2.53SG6的一示例，没有接口ACL ：
brisk#show run int g2/3
!
interface GigabitEthernet2/3
switchport mode access
switchport voice vlan 10
authentication host-mode multi-auth
authentication open
authentication order mab dot1x
authentication priority dot1x mab
authentication port-control auto
mab
然后，在主机验证后， DACL下载。它不会应用，并且授权发生故障。

在4500/6500的DACL
在4500/6500， DACL应用与acl_snoop DACLs。与4500个sup2 12.2.53SG6 (电话+ PC)的一示例显示此处。有语音(10)和数据的(100) VLAN分开的ACL ：

在此阶段PC和电话只响应对ICMP回音，但是接口ACL存在：
brisk#show ip access-lists interface g2/3
permit ip host 192.168.10.12 any
为什么？由于DACL仅争取电话(192.168.10.12)。对于PC，使用与Open模式的接口ACL ：
interface GigabitEthernet2/3
ip access-group all in
authentication open
brisk#show ip access-lists all
Extended IP access list all
10 permit ip any any (73 matches)
总之， acl_snoop为PC和电话将创建，但是DACL为电话返回。所以该ACL被看到作为对接口的已绑定的。
802.1x的MAC地址状态
当802.1x验证开始时， MAC地址仍然被看到作为动态，但是该数据包的操作是丢弃：
bsns-3750-5#show authentication sessions
Interface MAC Address Method Domain Status Session ID
Gi1/0/1 0007.5032.6941 dot1x UNKNOWN Running C0A8000100000596479F4DCE

在MAC地址变为的成功认证以后提供静态和端口号：

故障排除
切记读您的特定软件版本和平台的802.1x配置指南。
如果开TAC案例，请提供从这些命令的输出：
- show tech
- show authentication会话接口<xx>详细信息
- show mac address-table接口<xx>
收集SPAN端口数据包捕获和这些调试也是好的：
- debug radius verbose
- 调试epm全部
- debug authentication全部
- debug dot1x全部
- debug authentication功能<yy>全部
- debug aaa authentication
- debug aaa authorization
