SUMMARY STEPSĮnters configuration mode for the loopback interface. To configure a loopback interface, follow these steps, beginning in global configuration mode. The loopback interface acts as a placeholder for the static IP address and provides default routing information. Sets the IP address and subnet mask for the specified GE interface.Įnables the GE interface, changing its state from administratively down to administratively up.Įxits configuration mode for the GE interface and returns to global configuration mode. Note GigabitEthernet WAN Interfaces are 0/8 and 0/9 for Cisco C841M-8X ISR and 0/4 to 0/5 for Cisco C841M-4X Router(config)# interface gigabitethernet 0/8Įnters the configuration mode for a Gigabit Ethernet interface on the router. To configure Gigabit Ethernet (GE) WAN interfaces, follow these steps, beginning in global configuration mode.

Reversed Polarity: If Mag-jack RJ45 connector has no dots or digit marked on front housing, it can be used with coupler and short cable (Cat5E UTP cable) to connect other devices which doesn’t support auto polarity correction.

Straight Polarity: If Mag-jack RJ45 connector has a dot or digit marked on front housing, it can be used with any type of cables.

You can connect WAN interfaces either by using straight polarity connectors or reversed polarity connectors. Specifies an encrypted password to prevent unauthorized access to the router.ĭisables the router from translating unfamiliar words (typos) into IP addresses.Ĭonfiguring Gigabit Ethernet WAN Interfaces SUMMARY STEPSĮnters global configuration mode, when using the console port. To configure the global parameters for your router, follow these steps.
