Cisco ASR 9000 Series System Configuration Guide

Limitations of Layer 2 Fabric Network Topology
1
Bundle interfaces are not supported in Layer 2 Fabric architecture. In the Layer 2 Fabric topology, bundle
ICL is not supported but sat-ether port bundle is supported.
2
Point to Multi-point Layer 2 cloud is not supported.
3
A Satellite can support only one encapsulation on a given physical interface. So, the Layer 2 fabric
connections from both hosts must be configured with the same encapsulation type.
4
A Satellite cannot support multiple Layer 2 fabric connections with the same VLAN on the same physical
ICL interface.
5
When Satellite ethernet bundle interfaces are configured on the access ports, the bundle wait timer needs
to be configured to zero to get better convergence.

Cisco ASR 9000v has these limitations on the Layer 2 Fabric network topology:
•
The usable VLAN range is from 2 to 4093.
•
Only four 10 Gigabit Ethernet ICLs can be used on the ports 1/45 to 1/48.
•
Only two 1 Gigabit Ethernet ICLs can be used on the ports 1/45 and 1/46.
•
Only 44 satellite ports are present (namely, Gig1/1 to Gig1/44).
7
Cisco ASR 901 has these limitations on the Layer 2 Fabric network topology:
•
The usable VLAN range is from 2 to 4094.
•
Only two 1 Gigabit Ethernet ICLs can be used (Gig0/10, Gig0/11). However, from Release 5.2.2
onwards, any two ports of the 12 available ports can be configured as ICL. Remaining 10 ports are
satellite ports.
8
When a single physical ICLs is connected on both hosts and multiple physical ICLs are connected on
satellite, the following limitations are applied:
