Information About Ingress Classification
• SIP-based classification—SPAs rely on the classification performed inside the CC.
The SPAs supported on a Cisco ASR 1000 Series Router can be broadly classified into the following
categories:
• Ethernet SPAs—Fast Ethernet (FE), 1-Gigabit Ethernet (GE), 10-Gigabit Ethernet SPAs
• ATM SPAs—OC3 and OC12 flavours
• Channelized SPAs—ChT1/ E1, ChT3/ DS0, ChSTM1/ OC3, and ChOC12/ DS0 SPAs
• Clear Channel SPAs—T3/ E3 and 12-in-1 SPAs
• POS SPAs—OC3, OC12, OC48, and OC192 flavors
Note The Ethernet and ATM SPAs have classification capability at the SPA level, while the other types of
SPAs rely on the SIP for ingress classification.
Table 27-5 shows the classification models followed by the various SPAs:
