In summary, the valid values to set for speed in the command line for
1000Base-T are: 10HD, 10FD, 100HD
, 100FD, 1000FD, and auto_on.
The speed value can take one of three formats. In the human-readable for-
mat, it is of the form:
[speed {
Full | Half}
Duplex](Autonegotiation :
{On | Off})
Example:
1 Gbps Full Duplex (Autonegotiation : On)
.
Note that the speed and duplex may not be present in some situations.
In the script-friendly output, the speed value is of the form:
[speed {
FD|HD}]
auto_{on|off}
Examples:
1000FD auto_on
100HD auto_off
Note that the speed and duplex are optional in the scriptable output also: they
may not be present in some situations.
In the configuration file, there is an additional twist, because there are
separate variables for speed-duplex and autonegotiation. For 1000Base-T, the
HP_IGELAN_SPEED variable can contain one of the values
10HD, 10FD,
100HD, 100FD, and auto_on (same as the command line values). The
HP_IGELAN_AUTONEG variable is of no relevance.
For 1000Base-SX, the HP_IGELAN_SPEED is irrelevant, while the
HP_IGELAN_AUTONEG has values of either Off (same as 0) or On (same as
1), indicating autonegotiation being off or on, respectively.
Note that speeds below 1 Gbps are allowed only if MTU is 1500 bytes or less.
send_coal_ticks Max Send Coalesce Ticks: Maximum time for the NIC to wait after sending a
frame before it raises an interrupt. This and other interrupt tunables must be
modified with care.
Minimum: 0
Maximum: 10000000
Default: 150.
send_max_bufs Max Send Buffers: Maximum number of send descriptors for the NIC to
coalesce before it raises an interrupt. This and other interrupt tunables must
be modified with care.
Minimum: 1
Maximum: 128
Default: 10
tx_cko Transmit Checksum Offload: Hardware TCP/UDP (IPv4) transmit checksum
offload.
Values:Off,On.
Default: Off
vmtu Virtual MTU for TCP Segmentation Offload (TSO). Setting it to zero disables
TSO. Setting it to a non-zero value enables TSO.
Values: 0, 32160
Default: 0
USAGE
Display Network Interfaces
This command displays network interface without any arguments.
nwmgr
The command without any arguments displays all the network interfaces in the system, including
physical LAN interfaces (NICs), virtual LAN interfaces (VLANs and APA aggregates), and RDMA-
based interfaces.
