Chapter 4 Cisco ASR 1000 Series Router SPA Interface Processors (SIPs)
Cisco ASR 1000 Series SPA Interface Processor
Cisco ASR 1000 Series SPA Interface Processor
This section describes the Cisco SPA interface processors for the Cisco ASR 1006, Cisco ASR 1004,
Cisco ASR 1002, and Cisco ASR 1013 routers. The Cisco ASR 1000 Series Routers support the
following Cisco ASR 1000-SIPs:
•
Cisco ASR 1000-SIP10—This SIP supports:
–
4 half height (¼ Rate or full rate or combination) SPAs with up to 16 ports per SPA
–
2 full height (¼ Rate or full rate or combination) SPAs with up to 32 ports per SPA
–
2 half height and 1 full height comb in at on that does not exceed 64 ports
–
Up to 10 Gbps of oversubscription
•
Cisco ASR 1000-SIP40—This SIP supports:
–
4 half height (¼ Rate or full rate or combination) SPAs with up to 24 ports per SPA
–
2 full height (¼ Rate or full rate or combination) SPAs with up to 48 ports per SPA
–
2 half height and 1 full height combination that does not exceed 96 ports
–
Up to 40 Gbps aggregate bandwidth from the four SPA bays
–
ESI bandwidth of 11 to 46 Gbps
–
Ingress buffering at 128 MB and egress buffering at 6MB
For information about what hardware is supported and compatible and not compatible with the new ASR
1000 40G components and Cisco ASR 1013 Router, see
Table 2-4
and
Table 2-3
.
The Cisco SPAs provide the physical interfaces for router connectivity ranging from copper,
channelized, POS, ATM and Ethernet. The Cisco ASR 1000 Series SIP provides the physical termination
for the SPAs and accepts up to four half-height and 2 full height Cisco SPAs.
The is a list of characteristics of the Cisco ASR 1000 Series SPA Interface Processors for the Cisco ASR
1006, Cisco ASR 1004, and Cisco ASR 1013 routers:
•
A SIP is a carrier card that inserts into a router slot like a line card. It provides no network
connectivity on its own.
•
A SIP contains one or more subslots, which are used to house one or more SPAs. The SPA provides
interface ports for network connectivity.
•
During normal operation, the SIP should reside in the router fully populated either with functional
SPAs in all subslots, or with a blank filler plate (SPA-BLANK=) inserted in all empty subslots.
•
SIPs support online insertion and removal (OIR) with SPAs inserted in their subslots. SPAs also
support OIR and can be inserted or removed independently from the SIP.
Note
Fully populate all slots and subslots with blank filler plates or functional SPAs for maximum efficiency
of the cooling system.
