DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Usage Guideline The IPv4 address of an interface can be either manually assigned by the user or dynamically assigned by the DHCP server. For manual assignment, the user can assign multiple networks to a VLAN, each with an IP address. Among these multiple IP addresses, one of them must be the primary IP address and the rest are secondary IP address. The primary address will be used as the source IP address for SNMP trap messages or SYSLOG messages that are sent out from the interface. Use the no ip address command to delete the configured IP address entry. Example This example shows how to set 10.108.1.27 is the primary address and 192.31.7.17 and 192.31.8.17 are secondary addresses for VLAN 100. Switch# configure terminal Switch(config)# interface vlan100 Switch(config-if)# ip address 10.108.1.27 255.255.255.0 Switch(config-if)# ip address 192.31.7.17 255.255.255.0 secondary Switch(config-if)# ip address 192.31.8.17 255.255.255.0 secondary Switch(config-if)# 9-7 ip proxy-arp This command is used to enable the proxy ARP option for an interface. Use the no form of this command to revert to the default setting. ip proxy-arp no ip proxy-arp Parameters None. Default By default, this option is disabled. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline Use this command to configure the proxy ARP state for an interface. When proxy ARP is enabled, the system will respond to ARP requests for IP addresses within the local connected subnets. Proxy ARP can be used in the network where hosts have no default gateway configured. Example This example shows how to enable proxy the ARP feature on the interface of VLAN 100. 131
