Can multiple IP addresses be configured for the U1900?

108

The number of IP addresses configured for the U1900 is determined by the network port mode of the U1900 control board . The U1911, U1960, U1980, and U1981 support configuration of the network port mode on their control boards.
The SCU board (U1911/U1960/1981) and SMCU board (U1980) support three network port modes: single-network-port mode, dual-network-port mode, and triple-network-port mode.
In single-network-port mode, port 0 and port 1 work in active/standby mode. Port 2 is not used.
In dual-network-port mode, port 0 processes the management traffic (the port is connected to the BMU, eSight, and LMT) and connects to the CDR server. Port 1 processes all service data streams and connects to the CDR server. Port 2 is not used. Two IP addresses are configured in this mode.
In triple-network-port mode, port 0 processes the management traffic (the port is connected to the BMU, eSight, and LMT) and connects to the CDR server. Port 1 processes all service data streams and connects to the CDR server. Port 2 connects to the CDR server. Three IP addresses are configured in this mode.

Number of virtual IP addresses of VRRP groups that can be configured on the USG6000

Example for configuring VRRP load balancing (configuring multiple virtual IP addresses) Requirements: USG_A serves as the Master of VRRP group 1 and the Backup of VRRP group 2. USG_B serves as the Master of VRRP group 2 and the Backup of VRRP group 1. On the internal network, HostA uses VRRP group 1 as the gateway, and HostC uses VRRP group 2 as the gateway. This helps implement load balancing and mutual backup. Configuration roadmap 1. Create two VRRP groups at GigabitEthernet 0/0/2 of USG_A. USG_A serves as the Master of VRRP group 1 and the Backup of VRRP group 2. 2. Create two VRRP groups at GigabitEthernet 0/0/2 of USG_B. USG_B serves as the Backup of VRRP group 1 and the Master of VRRP group 2. Operation steps 1. Configure VRRP. # Configure GigabitEthernet0/0/2 on USG_A, create VRRP group 1, and set the priority of USG_A in VRRP group 1 to 105 (as the Master). Create VRRP group 2 and set the priority of USG_A in VRRP group 2 to the default value 100 (as the Backup). system-view [USG_A] vrrp mode [USG_A] interface GigabitEthernet 0/0/2 [USG_A-GigabitEthernet0/0/2] ip address 10.1.1.1 24 [USG_A-GigabitEthernet0/0/2] vrrp vrid 1 virtual-ip 10.1.1.111 [USG_A-GigabitEthernet0/0/2] vrrp vrid 1 priority 105 [USG_A-GigabitEthernet0/0/2] vrrp vrid 2 virtual-ip 10.1.1.112 # Configure GigabitEthernet0/0/2 on USG_B, create VRRP group 1, and set the priority of USG_B in VRRP group 1 to the default value `100 (as the Backup).

How do U1900 series unified gateways support multiple IP addresses, with one private IP address and one public IP address

The U1911/U1960/U1980/U1981 supports multi-network-port work mode to separate the service and management data. In general, the gateways work in single network port mode, and the first two network ports of a gateway work in active/standby mode. In multi-network-port mode, only network port 0 can be used to manage and maintain the device. Other voice gateways do not support multiple IP addresses, and the first two ports work in active/standby mode.
