sFlow Source IP Address Configuration Notes
- The first IP address in the interface IP address list is considered the source IP address.
- If the sFlow destination is IPv6, and the sFlow source is configured for an IPv6 address, then an IPv6 address is selected from the configured interface.
- If the sFlow destination is IPv4, and the sFlow source is configured for an IPv4 address, then an IPv4 address is selected from the configured interface.
- At any point in time, only one source of the Ethernet, VE, or loopback interface can be specified as the source interface.
- Upon configuring another source for an IPv4 or IPv6 address, any previously configured source for the IPv4 or IPv6 address is deleted.
- If the source IP address is not configured, by default, the IP address of the outgoing interface is used in the sFlow datagram.
- You can configure IPv4 and IPv6 source interfaces independently.
- A LAG virtual interface or any member ports of the LAG cannot be configured as an sFlow source.
- The sFlow source IP address configuration is supported on sFlow version 2 and sFlow version 5 and is valid only for the router build.
- Addition and deletion of IPv4 and IPv6 addresses on an sFlow source interface triggers
the following events:
- If the added IP address is the first IP address in the table, then it is considered as the source IP address.
- If the added IP address is positioned on top of the IP table (due to IP address sequence order), then it is reassigned as the source IP address.
- If the IP address that is used as the source IP address is deleted, the next IP address on the same interface is considered as the source IP address.
- If all the IP addresses are deleted from the source interface, the IP address of the outgoing interface is used in the sFlow datagram.
