Hi, Just want to ask on how to check and change the MTU size of the nodes from 1500 to 9000? I need to match the MTU size of some cluster nodes which has 1500 to the others with 9000 because they are inconsistent. Thanks (1 Reply)
Hi,
Curious problem with IPV6. Situation is wget request from squid proxy via intermediate router. With IPV4 (wget -4) speed is ~100MB/sec. With IPV6 (wget -6) it drops to 30KB/sec.
Examining the traffic with tcpdump shows that the squid box is regularly sending out over-sized packets (>MTU)... (5 Replies)

Hi Al,
In course of understanding networking in Solaris, I have these doubts on Interfaces. Please clarify me. I have done fair research in this site and others but could not be clarified.
1. In the "ifconfig -a" command, I see many interfaces and their configurations. But I see many... (1 Reply)
Couldn't find an IRIX forum, so I'm posting to this one...
Just had our SAs rebuild an IRIX machine and now I need to set the MTU to 1344 (vice 1500 default). I can set it manually using the ifconfig command, but it won't survive a reboot. I made an entry into the /etc/init.d/ifconfig-1.options... (0 Replies)

ntxn(7D) Devices ntxn(7D)NAME
ntxn - NetXen 10/1 Gigabit Ethernet network driver
SYNOPSIS
/dev/ntxn*
DESCRIPTION
The ntxn 10/1 Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider
Interface, dlpi(7P), on NetXen 10/1 Gigabit Ethernet controllers.
The ntxn driver functions include chip initialization, frames transmit and receive, promiscuous and multicast support, TCP and UDP checksum
off-load (IPv4) and 9600 bytes jumbo frame.
The ntxn driver and hardware support the 10GBASE CX4, 10GBASE-SR/W, LR/W, and 10/100/1000BASE-T physical layers.
APPLICATION PROGRAMMING INTERFACE
The cloning character-special device, /dev/ntxn, is used to access all NetXen devices installed within the system.
The ntxn driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of ntxn instances and for ntxn
instances to be aggregated. See dladm(1M) for more details.
The values returned by the driver in the DL_INFO_ACK primitive in response to your DL_INFO_REQ are:
o Maximum SDU is 9600.
o Minimum SDU is 0.
o DLSAP address length is 8.
o MAC type is DL_ETHER.
o SAP (Service Access Point) length value is -2, meaning the physical address component is followed immediately by a 2-byte SAP
component within the DLSAP address.
o Broadcast address value is the Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
CONFIGURATION
By default, the ntxn driver works without any configuration file.
FILES
/dev/ntxn* Special character device.
/kernel/drv/ntxn 32-bit device driver (x86).
/kernel/drv/amd64/ntxn 64-bit device driver (x86).
