故障排除
.
配置
1.启用IOX。
Switch#conf terminal Switch(config)#iox Switch(config)#
等待1-5分钟，使IOX初始化。确保IOX正常运行。您可以检查CLI会话期间显示的消息，也可以查看show命令的输出。
*Mar 10 15:35:40.206: %UICFGEXP-6-SERVER_NOTIFIED_START: Switch 1 R0/0: psd: Server iox has been notified to start *Mar 10 15:35:51.186: %IOX-3-PD_PARTITION_CREATE: Switch 1 R0/0: run_ioxn_caf: IOX may take upto 5 mins to be ready. Wait for iox to be ready before installing the apps *Mar 10 15:37:56.643: %IOX-3-IOX_RESTARTABITLITY: Switch 1 R0/0: run_ioxn_caf: Stack is in N+1 mode, disabling sync for IOx restartability *Mar 10 15:38:05.835: %IM-6-IOX_ENABLEMENT: Switch 1 R0/0: ioxman: IOX is ready. Switch#show iox-service IOx Infrastructure Summary: --------------------------- IOx service (CAF) : Running IOx service (HA) : Running IOx service (IOxman) : Running IOx service (Sec storage) : Running Libvirtd 5.5.0 : Running Dockerd v19.03.13-ce : Running Sync Status : Disabled
2.网络配置。
本示例使用AppGigabitEthernet接口提供网络访问。
! interface AppGigabitEthernet1/0/1 switchport trunk allowed vlan 50 switchport mode trunk ! app-hosting appid guestshell app-vnic AppGigabitEthernet trunk vlan 50 guest-interface 0 guest-ipaddress 192.168.10.10 netmask 255.255.255.0 name-server0 192.168.10.254 end !
注意：GuestShell使用静态IP地址，因为默认情况下它不包括DHCP客户端服务。您可以安装DHCP客户端服务以动态获取IP地址。
本示例使用管理接口(Gi0/0)提供网络访问。在管理模式中，Guestshell使用网络管理端口将Cisco IOS配置的管理端口IP地址用作网关。
! app-hosting appid guestshell app-vnic management guest-interface 0 name-server0 8.8.8.8 !
注意：使用管理接口时，Guestshell eth0接口的默认配置硬编码为IP地址192.168.30.2。
您可以配置虚拟端口组接口：
- 虚拟端口组配置：使用静态IP地址建立虚拟端口组。
- Internet 连接:确保前端口接口连接到Internet以允许外部访问。
- NAT 配置:在虚拟端口组和前端口之间设置NAT，以促进网络地址转换。
- GuestShell IP分配：将IP地址分配给与虚拟端口组接口位于同一子网内的GuestShell。
! interface VirtualPortGroup0 ip address 192.168.35.1 255.255.255.0 ip nat inside ! interface GigabitEthernet1/0/3 no switchport ip address 192.168.100.10 255.255.255.0 ip nat outside ! ip route 0.0.0.0 0.0.0.0 192.168.100.254 ip route vrf Mgmt-vrf 0.0.0.0 0.0.0.0 192.168.10.254 ip nat inside source static tcp 192.168.35.2 7023 192.168.100.10 7023 extendable ! ! ip access-list standard NAT_ACL 10 permit 192.168.0.0 0.0.255.255 ! app-hosting appid guestshell app-vnic gateway1 virtualportgroup 0 guest-interface 0 guest-ipaddress 192.168.35.2 netmask 255.255.255.0 app-default-gateway 192.168.35.1 guest-interface 0 name-server0 8.8.8.8 end
3.启用guestshell。
Switch#guestshell enable Interface will be selected if configured in app-hosting Please wait for completion guestshell installed successfully Current state is: DEPLOYED guestshell activated successfully Current state is: ACTIVATED guestshell started successfully Current state is: RUNNING Guestshell enabled successfully
注意：guestshell enable命令是安装guestshell的唯一方法。使用应用托管CLI激活/连接/停用可用于控制guestshell。建议您改用guestshell exec CLI。
Guestshell生命周期
Guestshell disable:Disable guesthell会删除对guestshell的访问并终止当前会话。保留文件/数据，您可以使用guestshell enable恢复访问。
Switch#guestshell disable Guestshell disabled successfully
Guestshell destroy:这将以不可逆的方式删除访客shell文件系统。所有文件/数据/脚本/设置外壳/已安装的软件包和模块。
Switch#guestshell destroy Guestshell destroyed successfully
注意：运行此命令时，所有数据都会不可逆地丢失。
Guestshell运行：Guestshell运行命令guestshell run bash在Guest Shell中创建一个shell，允许您在/bin和/sbin下使用任何Linux二进制文件。
Switch#guestshell run bash [guestshell@guestshell ~]$ ping 192.168.10.1 PING 192.168.10.1 (192.168.10.1) 56(84) bytes of data. 64 bytes from 192.168.10.1: icmp_seq=2 ttl=254 time=0.517 ms 64 bytes from 192.168.10.1: icmp_seq=3 ttl=254 time=0.552 ms 64 bytes from 192.168.10.1: icmp_seq=4 ttl=254 time=0.447 ms 64 bytes from 192.168.10.1: icmp_seq=5 ttl=254 time=0.549 ms
Guestshell运行python:使用此命令启动交互式python解释程序。
Switch#guestshell run python3 Python 3.6.8 (default, Dec 22 2020, 19:04:08) [GCC 8.4.1 20200928 (Red Hat 8.4.1-1)] on linux Type "help", "copyright", "credits" or "license" for more information. >>>

注意：在交换机上，资源大小调整最多允许达到平台的最大限制，请参阅Cisco Catalyst 9000平台硬件资源应用。
常见情况
DHCP 配置
问题：DHCP客户端二进制(DHCLIENT)不存在。
解决方案
您可以使用Yum实用程序并使用sudo yum install dhcp-client命令来安装DHCP客户端。但是，请注意，CentOS Stream 8的存储库不再可用。
1.必须避免在应用托管中设置IP地址以允许DHCP正常工作。
! interface AppGigabitEthernet1/0/1 switchport trunk allowed vlan 50 switchport mode trunk ! app-hosting appid guestshell app-vnic AppGigabitEthernet trunk vlan 50 guest-interface 0 name-server0 8.8.8.8 !
2.将mirrorlist更改为yum repo中的baseurl vault。
Switch#guestshell run bash
[guestshell@guestshell ~]$ sudo find /etc/yum.repos.d/ -type f -exec sed -i 's/mirrorlist=/#mirrorlist=/g' {} +
[guestshell@guestshell ~]$ sudo find /etc/yum.repos.d/ -type f -exec sed -i 's/#baseurl=/baseurl=/g' {} +
[guestshell@guestshell ~]$ sudo find /etc/yum.repos.d/ -type f -exec sed -i 's/mirror.centos.org//g' {} +
[guestshell@guestshell ~]$ cat /etc/yum.repos.d/CentOS-Stream-RealTime.reporepo
# CentOS-Stream-RealTime.repo
# The mirrorlist system uses the connecting IP address of the client and the
# update status of each mirror to pick current mirrors that are geographically
# close to the client. You should use this for CentOS updates unless you are
# manually picking other mirrors.
#
# If the mirrorlist does not work for you, you can try the commented out
# baseurl line instead.
[rt]
name=CentOS Stream $releasever - RealTime
#mirrorlist=http://mirrorlist.centos.org/?release=$stream&arch=$basearch&repo=RT&infra=$infra
baseurl=http:///$contentdir/$stream/RT/$basearch/os/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
3.安装软件包。

注意：（对于CALO）可以为Yum配置代理。这允许Yum通过代理服务器连接进行软件包下载：
[guestshell@guestshell ~]$ echo "proxy=http://<IP_address:port>/" | sudo tee -a /etc/yum.conf > /dev/null
4..请求eth0的DHCP IP地址。
[guestshell@guestshell ~]$ sudo dhclient eth0
5.通过检查IP地址分配来验证DHCP客户端是否正常工作。
Switch#guestshell run ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.10.2 netmask 255.255.255.0 broadcast 192.168.10.255

DNF数据包管理器更新失败
问题：由于以下错误，无法在Guestshell上完成sudo dnf update -y:
[guestshell@guestshell ~]$ sudo dnf upgrade --refresh Warning: failed loading '/etc/yum.repos.d/CentOS-Base.repo', skipping.
解决方案
1.重新安装并升级RPM包。
! Clean packages [guestshell@guestshell ~]$ sudo dnf clean all ! Reinstall and update the tpm2-tss package: [guestshell@guestshell ~]$ sudo dnf install tpm2-tss-2.3.2-3.el8 [guestshell@guestshell ~]$ sudo dnf upgrade rpm
2.单独安装git软件包。
[guestshell@guestshell ~]$ sudo dnf install git -y
升级后丢失的Guestshell访问
问题：升级到版本17.08.01或更高版本后，Guest Shell变得不可访问，从而导致无法执行脚本。
Switch#guestshell run bash Switch#
解决方案
此问题与思科漏洞ID CSCwi63075相关 
，在交换机上启用FIPS时，在升级期间触发。
1.禁用FIPS。
Switch#configure terminal Switch(config)#no fips authorization-key FIPS: Authorization-key erased ONLY from the Flash. But the authorization-key is still operational. Use "reload" command for complete removal of key and to enter into non fips-mode. Make sure to remove fips key from all the members of the stack individually
2.您可以升级到包含修补程序、版本17.12.04或任何更高版本的其中一个版本。
限制IPv6编址
问题：此问题涉及在Cisco Guestshell环境中的接口上出现意外的IPv6地址。但是，并非有意配置。
在使用IPV4的交换机上观察到的配置如下：
! app-hosting appid guestshell app-vnic AppGigabitEthernet trunk vlan 50 guest-interface 0 guest-ipaddress 192.168.20.10 netmask 255.255.255.0 <-- IPv4 address configured app-default-gateway 192.168.20.1 guest-interface 0 app-resource profile custom name-server1 192.168.20.1 !
在Guestshell环境中运行ifconfig命令时，IPv4和IPv6地址都变为可见。
lat1-2-ssw01.gts#guestshell run bash
[guestshell@guestshell ~]$ sudo ifconfig
eth0: flags=4163 mtu 1500

解决方案
步骤 1：在Guestshell中禁用IPv6路由和编址。
lat1-2-ssw01.gts#guestshell run bash [guestshell@guestshell ~]$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1 [guestshell@guestshell ~]$ sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1 [guestshell@guestshell ~]$ sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1
步骤 2：检验IPv6是否已禁用。
[guestshell@guestshell ~]$ /sbin/ifconfig
eth0: flags=4163 mtu 1500
inet 192.168.20.10 netmask 255.255.255.0 broadcast 192.168.20.255

运行Python脚本时出现磁盘空间错误
问题：此问题涉及在Guestshell中的嵌入式事件管理器(EEM)上运行的Python脚本。由于磁盘空间不足，脚本失败，错误为：
guestshell run python3 /flash/guest-share/monitoring.py -rt True -bgp True
---- pushing bgp status ----
OSError: [Errno 28] No space left on device
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

logfile.close()
OSError: [Errno 28] No space left on device
! This error indicates that the disk space allocated for logging command executions within the Guestshell environment has been exhausted.
解决方案
要解决磁盘空间耗尽的问题，您需要增加Guestshell环境的持久磁盘大小：
1.修改应用资源配置文件，以增加持久磁盘的大小。
Switch(config-app-hosting)# app-resource profile custom Switch(config-app-hosting-profile)# persist-disk 100 Switch(config-app-hosting-profile)# cpu 800 Switch(config-app-hosting-profile)# memory 256 Switch(config-app-hosting-profile)# end
2.保存配置并启用/禁用guestshell。
Switch# write memory Switch#guestshell disable Guestshell disabled successfully Switch#guestshell enable Interface will be selected if configured in app-hosting Please wait for completion guestshell installed successfully Current state is: DEPLOYED guestshell activated successfully Current state is: ACTIVATED guestshell started successfully Current state is: RUNNING Guestshell enabled successfully
日志记录Syslog
可以在guestshell中运行以下命令以显示系统日志消息：
[guestshell@guestshell ~]$ sudo logger -p 1 "Priority 1" [guestshell@guestshell ~]$ sudo cat /var/log/messages Mar 11 02:05:24 localhost systemd[248]: user@0.service: Failed at step PAM spawning /usr/lib/systemd/systemd: Operation not permitted Mar 11 02:05:24 localhost systemd[1]: user@0.service: Failed with result 'protocol'.

跟踪日志
可以使用app-hosting move appid guestshell log到bootflash:folder_name来旋转文件。这可用于旋转到目标目录，但也会旋转到traceloguestshell目录。
Switch#app-hosting move appid guestshell log to bootflash: Successfully moved tracelog to flash:/ioxapploguestshell/iox_R0-0_R0-0.14195_0.20250311023831.bin.gz
注意：IOX guestshell.log始终是/tmp/rp/trace·下的活动tracelog文件。当此文件达到1MB时，会自动将其旋转为带有时间戳的bootflash:traceloguestshell/，并启动一个新文件。
