ASR 5000系列机箱PSC放置和配置要求，以确保正确的线卡功能
简介
本文档介绍在放置和配置方面必须满足的数据包服务卡(PSC)要求，以确保所有线卡在思科聚合服务路由器(ASR)5000系列机箱上都可用。
PSC配置和放置要求
PSC的放置和配置对线路卡的功能有一些要求。当您尝试使用端口以太网配置线卡端口时，可能会遇到故障：没有此类端口错误消息。
为使线路卡可用，其后的物理PSC必须将其模式配置为主用。如果PSC配置为备用模式，即使配置了足够的活动模式PSC可以连接到PSC，则线卡不可用，并报告就绪状态。这适用于全尺寸XGLC（万兆以太网线卡）和半尺寸线卡。最好通过示例来解释这一点。
在本例中，起始点是八个PSC中的七个配置为主用模式，而PSC 16配置为备用模式。此外，PSC 16通过早期迁移变为活动状态。注意下一输出中线卡32的状态，该状态物理连接到PSC 16(16 + 16 = 32)，并处于就绪状态。这是因为PSC 16配置为备用模式。

之后，PSC 16配置为主用模式：
[local]ASR5000-2(config)# card 16
[local]ASR5000-2(config-card-16)# mode active
[local]ASR5000-2(config-card-16)# end
这会导致PSC 4转换到主用模式，因为通过设计，系统会尝试激活配置为主用的PSC数量。它还导致线卡32转换到备用状态，从而允许其配置/使用并连接到PSC 16:

在下一输出中，PSC 16随后配置回备用模式，并且所连接的线卡32会转换回就绪状态。为避免意外会话丢失，在系统中作为预防措施，当PSC配置为备用模式时，它将保持活动状态，除非强制重启：
[local]ASR5000-2(config)# card 16
[local]ASR5000-2(config-card-16)# mode standby
[local]ASR5000-2(config-card-16)# end

如果线路卡已配置(no shutdown)，且其所连接的PSC已配置为备用模式，则线路卡的配置将永久丢失：
show config
...
port ethernet 32/1
no shutdown
vlan 30
#exit
#exit
[local]ASR5000-2# config
[local]ASR5000-2(config)# card 16
[local]ASR5000-2(config-card-16)# mode standby
[local]ASR5000-2(config-card-16)# end
show config
...
no config for port 32/1
尝试配置处于就绪状态的端口会导致Failure:无此类端口错误：
[local]ASR5000-2# config
[local]ASR5000-2(config)# port ethernet 32/1
Failure: no such port
[local]ASR5000-2(config)#
