Sso Model - Cisco Catalyst 4500 Series Configuration Manual

Chapter 7 Configuring Interfaces
FTP
If you want to use an Fa1 port for an FTP operation, configure the Fa1 port as the source interface for
FTP as follows:
Switch(config)# ip ftp source-interface fastEthernet1
SSH
If you want initiate SSH from your switch through the Fa1 port, enter the following command:
Switch# ssh –l login name -vrf mgmtVrf ip address
For example:
Switch# ssh –l xyz -vrf mgmtVrf 20.20.20.1

SSO Model

On a redundant chassis, management port behavior differs from that of a standard Ethernet port in that
each supervisor engine possesses a management port, and only the port on the active supervisor engine
is enabled. The management port on the standby supervisor engine is always disabled; it cannot switch
any kind of traffic.
When a switchover occurs, the management port of the standby supervisor engine (now, active) is
enabled and can be used to switch traffic, while the management port on the "old" active supervisor
engine is disabled.
Note The Cisco IOS configuration for the management port is synchronized between the two supervisor
engines. Under Cisco IOS, they possess the same IP address. To avoid address overlapping during a
switchover on a redundant chassis, you should assign a different IP address on the management port from
the one you assigned to the same port in the ROMMON configuration.
ISSU Model
In SSO mode, the running configurations on the active and standby supervisor engines must match. You
cannot enable the management port on a redundant chassis if one of the two supervisor engines is
running an Cisco IOS image prior to Cisco IOS Release 12.2(50)SG (wherein a management port is not
supported).
When you perform an ISSU upgrade or downgrade between Cisco IOS Release 12.2(50)SG and a
software image prior to Cisco IOS Release 12.2(50)SG, we automatically disable the management port.
The port configuration is restored when both software images running on the supervisor engines are at
least Cisco IOS Release 12.2(50)SG. A warning message is also displayed.
