FlexWan lost config and upgrade ROMMON for 65/76

问题:

由于最近遇到了一个故障,重启后FlexWan的配置会丢失。
观察到的现象感觉是配置先刷,板卡随后重启,这样导致没有配置。
“copy start run” 可以暂时解决这个问题。
经过确认后这是一个软件BUG:CSCsq77835,需要升级ROMMON的版本才能完全解决。
ROMMON升级不是常事,所以接触的人不是很多,其实操作起来比较简单。
整理了详细的操作步骤,已作日后参考:
注:关于BUG的信息,可以去思科的BUG Toolkit上查询(需要CCO帐号)

6000W Power ISSUE

问题:

Customer have two 2500W power, now customer want to replace the 6000W power.
Customer want to check whether impact the business when replace the 6000W.

解决:

If customer have power usage exceeds need the downtime, as some of the linecards will go down due to lack of power. In case you have less than 2500w usage on the router, then follow the below steps.

1. have your power supply in redundant mode.
2. pull the power supply which is not active

密码保护:7600/6500 Architecture Summarize

这是一篇受密码保护的文章,您需要提供访问密码:

7600/6500 L3 sub-interface Limited

环境:

76做汇聚层交换机。

问题:

客户在2口上开启3层功能,应用单臂路由来提供vlan间的路由。当配置到封装类型时报错:

C7609-2(config-subif)#interface GigabitEthernet1/1.1
C7609-2(config-subif)# encapsulation dot1Q 11
Command rejected: VLAN 11 cannot be allocated. VLANs 1-1005 are VTP VLANs
VTP mode is client or server and must be changed to Transparent to use VLANs 1-1005
C7609-2(config-subif)# ip address 10.171.0.93 255.255.255.252

% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.

解决问题:

在交换机上,在2层端口上启用3层功能是受限制的,根据版本及硬件不同,限制也有所差别。现在拿65和76举例。

7609 Vlan Virtual-Port

环境:

7609做接入层交换机,下联DSLAM,上联核心,其余的是2层应用。

问题:

Console 有log告警,并且只出现几次,分别是module8 和module9,具体告警如下所示:

%PM-SP-STDBY-4-LIMITS: The number of vlan-port instances on module 8 exceeded the recommended limit of 1800
%PM-SP-4-LIMITS: The number of vlan-port instances on module 8 exceeded the recommended limit of 1800
%PM-SP-STDBY-4-LIMITS: The number of vlan-port instances on module 9 exceeded the recommended limit of 1800
