cisco WS-C4900M: Set SSH
--- author: Tom Lasswell date: updated: read: 1 min in: [engineering] tags: [cisco, ssh] ---
Just a quick note about configuring SSH on a Cisco Catalyst 4900M Switch:
Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500e-ENTSERVICESK9-M), Version 12.2(54)SG, RELEASE SOFTWARE (fc3)
# conf t
(config)#crypto key zeroize rsa
% No Signature RSA Keys found in configuration.
(config)# crypto key generate rsa general-keys label ssh modulus 1024
The name for the keys will be: ssh
% The key modulus size is 1024 bits
% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]
(config)# ip ssh authentication-retries 5
(config)# ip ssh version 2
(config)# line vty 0 4
(config)# transport input ssh telnet
Note: You can leave the “telnet” off vty transport, but if you do ensure that you’ve tested SSH first!
