Edge switch cabling guide

This document helps network administrators and support personnel connect edge switch management network.

Quick Summary

In some larger systems site connections are moved from spine to dedicated edge switches which allows for HSN (high speed network) to be cross connected allowing for alternative path to connect storage to customers site network.

Currently supported edge switch models:

Network topology

Network with edge switch:

  graph TD;
      Site-connection-->sw-edge-001;
      Site-connection-->sw-edge-002;
      sw-edge-001-->sw-spine-001;
      sw-edge-001-->sw-spine-002;
      sw-edge-002-->sw-spine-001;
      sw-edge-002-->sw-spine-002;

Network without edge switch:

  graph TD;
      Site-connection-->sw-spine-001;
      Site-connection-->sw-spine-002;

How does edge switch connect to Shasta management network

Typically edge switches connects in Shasta management network to the spine switches (sw-spine-00x) and to customers site network.

In Shasta management network this would be called a CHN deployment. Where as management network without edge switches would be use CAN deployment type.

Please note that Site connections today are considered “custom configuration” as IP addressing and site specific cabling is beyond the scope of Shasta management network.

To generate a custom configuration that can be applied via CANU

CANU custom switch configuration

How edge switch and site connections are in SHCD

CHN: The table below is an example of how the edge switch entry in the SHCD should appear if edge switches are present

Note Edge switches would have their own tab in SHCD called “edge”.

sw-25g02	x8000	u37	36	SITE	SITE	SITE		0
