Access network properties

The access network has the properties listed below.

IP mode (either IPv4 or IPv6)

By default, the access network has an IP mode of IPv4.

IPv4-specific properties:

IPv4 gateway address

This is the address from which communications initiated by the S Series Node are sent when the access network is the selected network for the particular type of communication and IPv4 addressing is selected.

By default, the access network has an IPv4 gateway address of 10.0.0.254.

IPv4 subnet

With the Management Console, you use the IPv4 gateway address and a four-octet subnet mask to specify the IPv4 subnet. With the management API, you use CIDR notation to specify the IPv4 subnet.

By default, the access network has an IPv4 subnet of 10.0.0.0/24 and a four-octet subnet mask of 255.255.255.0.

Physical IPv4 address for each server module

By default, the access network has physical IPv4 addresses of 10.0.0.1 for server module 1 and 10.0.0.2 for server module 2.

Virtual IPv4 address for each server module

By default, the access network virtual IP addresses are not set. These IP addresses must be set during the initial on-site configuration of the S Series Node.

IPv6-specific properties:

Primary IPv6 gateway address

This is the address from which communications initiated by the S Series Node are sent when the access network is the selected network for the particular type of communication and primary IPv6 addressing is selected.

Primary IPv6 subnet

With the Management Console, you use the primary IPv6 gateway address and an IPv6 prefix length to specify the primary IPv6 subnet. With the management API, you use CIDR notation to specify the primary IPv6 subnet.

Primary physical IPv6 address for each server module

These IP addresses must be set during the initial on-site configuration of the S Series Node.

Primary virtual IPv6 address for each server module

These IP addresses must be set during the initial on-site configuration of the S Series Node.

Optionally, secondary IPv6 settings

Gateway address, subnet, physical address for each server module, and virtual address for each server module.

With the Management Console, you use the secondary IPv6 gateway address and an IPv6 prefix length to specify the secondary IPv6 subnet. With the management API, you use CIDR notation to specify the secondary IPv6 subnet.

Combined speed and duplex

By default, the access network has a speed and duplex setting of auto. With this setting, the S Series Node detects the speed and duplex settings of the device with which it's communicating. The S Series Node then adjusts its own settings to provide the highest possible data rate.

Alternatively, the speed and duplex setting can be:

• If the access network ports are 25Gb SFP28: 25GbE Full
• If the access network ports are 25Gb SFP28 but are connected to a 10Gb SFP+ networking infrastructure: 10GbE Full
• If the access network ports are 10Gb SFP+ or 10GBase-T: 10GbE Full

Maximum transmission unit (MTU)

The MTU is the largest packet size supported for data sent on the network.

The MTU for a network can be 1,500 or 9,000. The larger MTU reduces overhead and increases network throughput. An MTU of 9,000 is possible only if it is supported by the networking infrastructure.

By default, the access network has an MTU of 1,500.

Bonding mode and transmit hash policy

The bonding mode and transmit hash policy can be:

• active-backup
• 802.3ad (layer 2+3)
• 802.3ad (layer 3+4)

By default, the access network has a bonding mode of active-backup.

VLAN ID

If the networking infrastructure supports virtual networking, valid values for the VLAN ID are integers in the range 0 through 4,094. If the networking infrastructure doesn't support virtual networking, the VLAN ID must be 0.

If the access network has a nonzero VLAN ID, the applicable switches must be configured to support that ID. Additionally, the networking infrastructure must be configured to allow client requests to be routed to the S Series Node through the access network.

By default, the access network has a VLAN ID of 0.

Connection expectation for each port on each server module

The connection expectation for an access network port can be On (connection expected) or Off (connection not expected). If a server module has a two-port 25Gb Ethernet SFP28 PCIe card installed in it, you set connection expectations for ports 0 and 1. Otherwise, you set connection expectations for ports 0, 1, 2, and 3.

The S Series Node issues an alert if:

• A port is expected to be connected (that is, the port setting is On) but is not connected to an active port on a network switch.
• A port is not expected to be connected (that is, the port setting is Off) but is connected to an active port on a network switch.

By default, the connection expectation for each port is On.
