Campus Fabric Configuration Guidelines
Consider the following guidelines and limitations when configuring campus fabric elements:
• Configure no more than 3 control-plane devices in each fabric domain.
• Configure no more than 2 border devices in each fabric domain.
• Each fabric edge device supports up to 2000 endpoints.
• Each control-plane device supports up to 5000 fabric edge device registrations.
• Configure no more than 32 virtual contexts in each fabric domain.
• Ensure that you use 10-Gigabit-Ethernet supervisor uplinks when configuring underlay 
connectivity.
Limitations and Restrictions
• You can configure Cisco Catalyst 4500-E series switches as edge devices only.
• Campus Fabric is not supported in Virtual Switching System (VSS) mode and in VSS wireless 
mode. 
• Virtual Extensible LAN (VXLAN) encapsulation is supported on the Supervisor uplink modules 
only. Ensure that you use supervisor uplink modules for underlay connections between fabric 
elements. 
• Campus Fabric is supported only on Cisco Catalyst 4500-E series switches, on Supervisor Engine 
8-E.
• IPv6 hosts are not supported in the fabric domain.
• Policy-based routing (PBR) and Web Cache Communication Protocol (WCCP) are not supported 
within the fabric domain.
• Cisco TrustSec SGT Exchange Protocol (SXP) cannot be used to propagate SGTs across devices 
within the fabric domain. 
• On the edge device, Cisco TrustSec links are not supported only on uplink interfaces connected to 
the underlay.
• Layer 3 source group tags cannot be applied to uplink interfaces connected to the underlay.
