How many vPC can be configured in Nexus switches?
You can have only two devices as vPC peers; each device can serve as a vPC peer to only one other vPC peer. The vPC peer devices can also have non-vPC links to other devices. See the following figure for invalid vPC peer configurations.
How many vPC domains can a switch have?
The maximum number of switches in a vPC domain is two. The maximum number of vPC peers per switch or VDC is one. When Static routing from a device to vPC peer switches with next hop, FHRP virtual IP is supported. Dynamic routing adjacency from vPC peer switches to any Layer3 device connected on a vPC is not supported.
Does Nexus 3k support vPC?
Cisco Nexus 3000 Series Switch vPC Topology You can connect a pair of Cisco Nexus 3000 Series switches in a vPC directly to another switch or to a server. Up to 8 interfaces could be connected to each Cisco Nexus 3000 Series switch providing 16 interfaces bundled for the vPC pair.
What is the use of vPC peer link?
A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses. Instances in either VPC can communicate with each other as if they are within the same network.
Can a Cisco Nexus 5548 switch perform layer 3 forwarding?
When you use a Cisco Nexus 5548 switch or Cisco Nexus 5596UP switch as a default gateway for hosts, you can deploy the First Hop Redundancy Protocol (FHRP) to provide default gateway redundancy. Beginning with Cisco NX-OS Release 5.0 (3)N1 (1b), an active FHRP peer and a standby peer can perform Layer 3 forwarding when you enable vPC.
When to use layer 3 and VPC on Cisco Nexus 5500?
In a non-vPC topology, when the Layer 3 and SVI interfaces are down, the redundant Cisco Nexus 5500 Platform switch becomes the active peer for all FHRP groups and it continues to forward traffic. In a vPC topology, although the SVI interfaces are suspended, the vPC member ports are still up on the Cisco Nexus 5500 Platform switch.
Can a 5548 connect to a layer 3 router?
08-18-2011 10:58 AM 08-18-2011 10:58 AM I have a pair of 5548’s that I purchased with the layer 3 routing module as part of a bundle. I am trying to setup some layer 3 routing between a couple of SSVI’s but have not had any luck. From one VLAN I can ping both VLAN interfaces but I can not ping across to another host.
How are Nexus switches connected to VPC domain?
A pair of similar Nexus switches configured in a vPC domain. Three Layer 3 devices (L3-A, L3-B, and L3-C) connected to a pair of Nexus switches. L3-A is connected to an orphan port. L3-B and L3-C are connected with vPC to Nexus-A and Nexus-B. Nexus-A and Nexus-B have additional Layer2 and Layer3 links between them.
