WebJun 18, 2009 · On a Cisco Catalyst 3750 series switch, the jumbo frames are supported on the Gigabit Ethernet ports. The MTU cannot be changed on an individual interface. It must be set globally. The switch must be reset afterward in order for the MTU change to take effect. Consider this example: 3750 (config)#system mtu jumbo 9000. WebNov 7, 2024 · The system MTU setting is saved in the switch environmental variable in NVRAM and becomes effective when the switch reloads. Unlike the system MTU routing configuration, the MTU settings you enter with the system mtu and system mtu jumbo commands are not saved in the switch Cisco IOS configuration file, even if you enter …
