Setting IP Address and Subnet Mask
Ethernet control of SNP is managed through two RJ45-style gigabit ethernet connectors, Control A and
Control B. For the location of these connectors, see
Depending on whether you're using bonded mode or dual address mode, you will configure these
Ethernet management ports in one of the following ways.
•
Bonded Active/Backup mode (default): For best results use this option. Ports A and B have a
common IP address. The two Ethernet connections can be made to your network or switches with
no special configuration, since only one Ethernet port is active at any given time. This configuration
is used for redundancy, in case one of the links fails. For Control Link configuration, only Control A is
used.
•
Bonded LACP mode: Ports A and B have a common IP address, and traffic is balanced across the two
ports if both are available. The two Ethernet connections can be made to your network via managed
switches. This configuration is used for load-balancing and redundancy, in case one of the links fails.
For Control Link configuration, only Control A is used.
•
Dual Addresses: In this mode the device has two equivalent control plane ports, with distinct IP
addresses. The two ports should be on separate IP subnets and gateway addresses may be
configured for each port. All management & control protocols and services are available on both
ports concurrently.
Setting the Control Link mode is described in
To allow devices to communicate on a network, for best results set all SNP devices to the same subnet
(network location). When shipped, all SNP units are configured with the same default IP (device
identifier) and subnet addresses. These addresses need to be changed so that each unit is uniquely
identified and the network location of all units is accurately reflected. An IP address is made up of a
four-item set of numbers (octet). For a class C network, you must change the first three octets to
identify the location (address) of the unit on your network, and also change the last octet to uniquely
identify the device from other SNP units.
Defaults for Control A
Defaults for Control B
(only for Dual Address mode)
Note: For best results, set all SNP devices to the same subnet. Otherwise, you will also need to configure
Gateway settings.
Setting the IP Address at the SNP Front Panel
Depending on the setting for Network Mode, you may need to configure just Control A, or both Control
A and Control B.
Follow these steps to configure the network addresses at the SNP front panel:
