Connecting Irf Physical Interfaces; Binding Physical Interfaces To Irf Ports - HP 5130 EI series Configuration Manual

Connecting IRF physical interfaces

When you connect two neighboring IRF members, connect the physical interfaces of IRF-port 1 on one
member to the physical interfaces of IRF-port 2 on the other (see
For example, you have four chassis: A, B, C, and D. IRF-port 1 and IRF-port 2 are represented by A1 and
A2 on chassis A, represented by B1 and B2 on chassis B, and so on. To connect the four chassis into a
ring topology of A-B-C-D(A), the IRF link cabling scheme must be one of the following:
A1-B2, B1-C2, C1-D2, and D1-A2.
•
A2-B1, B2-C1, C2-D1, and D2-A1.
•
IMPORTANT:
No intermediate devices are allowed between neighboring members.

Connect the devices into a daisy-chain topology or a ring topology. A ring topology is more reliable
(see Figure 1
daisy-chain topology. Rather, the IRF fabric changes to a daisy-chain topology without interrupting
network services.

Binding physical interfaces to IRF ports

When you bind physical interfaces to IRF ports, follow these guidelines:
1). In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in
