Cisco ASR1000-SIP10 Oversubscription Guidelines

The total available bandwidth in your router ultimately depends on the features that you have enabled,
and the combination of hardware installed. This section describes some of the basic guidelines that you
can use to plan for a possible oversubscription on the Cisco ASR1000-SIP10.
Each Cisco ASR1000-SIP10 supports 4 single-height SPAs. The chassis models of the Cisco ASR 1000
Series Aggregation Services Routers support a different maximum number of SIPs as follows:
•
•
•
Each Cisco ASR1000-SIP10 has a 10 Gbps link to the Embedded Services Processor (ESP). Therefore,
there is an aggregate bandwidth limit—the sum of the total SPA bandwidth installed in the SIP—of 10
Gbps per SIP. This limit can be exceeded with the installation of some combinations of SPAs. See
Table 3-1
maximum bandwidth limitations of the ESP (5, 10, or 20 Gbps) depending on the ESP model installed.

Cisco ASR1000-SIP40 Oversubscription Guidelines

The total available bandwidth in your router ultimately depends on the features that you have enabled,
and the combination of hardware installed. However, this section describes some of the basic guidelines
that you can use to plan for a possible oversubscription on the Cisco ASR1000-SIP40.
Each Cisco ASR1000-SIP40 supports:
