DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide Example This example shows how to configure replacing the IPv4 packet priority to 4. Switch#configure terminal Switch(config)#mvlan vlan 100 Switch(config-mvlan)#replace-priority ipv4 4 Switch(config-mvlan)# 67-7 replace-source-ip This command is used to configure the source IP address which will be replaced into the reporting IGMP/MLD packet to uplink ports. Use the no form of this command to cancel the source address replacing. replace-source-ip {ipv4 IPV4-ADDRESS | ipv6 IPV6-ADDRESS} from { source | receiver | both} no replace-source-ip {ipv4 | ipv6} Parameters ipv4 IPV4-ADDRESS ipv6 IPV6-ADDRESS source receiver both Specifies the source IP address for IGMP control packet reporting up to routers. Specifies the source IP address for MLD control packet reporting up to routers. Specifies that the source IP address of the IGMP report/leave packet received on any multicast VLAN source port will be replaced. Specifies that the source IP address of the IGMP report/leave packet received on any multicast VLAN receiver port will be replaced. Specifies that the source IP address of the IGMP report/leave packet received on any port in the multicast VLAN will be replaced. Default None. Command Mode Multicast VLAN Configuration Mode. Command Default Level Level: 12. Usage Guideline The replace source IP option is used while reporting the join information towards the source port. The purpose is to avoid the control packets dropped by the uplink router due to IP spoofing checks. If the replacing address is configured, before forwarding the IGMP/MLD report/leave/done packet, sent by the host, the source IP address in the report/leave/done packet will be replaced by this IP address. Otherwise, the source IP address will not be replaced. 662
