Cisco SG300-52 Switch Standard Operating Procedure

This document defines operating standards, console connectivity, and cipher negotiation for the Cisco SG300-52 switch.

1. Device Overview

Hostname: switchf6eb8c
Firmware Version: v1.2.7.76
Management IP: 10.10.60.2 (VLAN 10 MGMT)
Management Protocols: SSH (Port 22), HTTP (Port 80)

2. SSH Access with Legacy Ciphers

Because firmware v1.2.7.76 requires legacy key exchange and cipher methods, use these parameters when connecting:

bash

ssh -o StrictHostKeyChecking=no \
    -o KexAlgorithms=+diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1 \
    -o HostKeyAlgorithms=+ssh-rsa \
    -c +aes128-cbc,aes256-cbc \
    cisco@10.10.60.2
