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.

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)

xge(7D) Devices xge(7D)NAME
xge - Neterion Xframe 10Gigabit Ethernet Network Adapter driver
SYNOPSIS
/dev/xge
DESCRIPTION
The xge 10 Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider
Interface, dlpi(7P), on S2IO Xframe 10-Gigabit Ethernet Network Adapter.
The xge driver functions includes controller initialization, frame transmit and receive, promiscuous and multicast support, TCP and UDP
checksum offload (IPv4 and IPv6), 9622-byte jumbo frame, and error recovery and reporting.
The xge driver and hardware support the 10GBase-SR/W, LR/W, and ER/W 802.3 physical layer.
APPLICATION PROGRAMMING INTERFACE
The cloning, character-special device /dev/xge is used to access all Xframe devices installed within the system.
The xge driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of xge instances and for xge
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 the DL_INFO_REQ are as follows:
o Maximum SDU is 9600.
o Minimum SDU is 0.
o DSLAP address length is 8 bytes.
o MAC type is DL_ETHER.
o SAP 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 Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
CONFIGURATION
By default, the xge driver works without any configuration file.
You can check the running-time status of a device instance using ndd(1M). Currently, the driver provides an interface to print all hard-
ware statistics.
For example, to print statistics of device xge0:
#ndd /dev/xge0 stats
tmac_data_octets 772
tmac_frms 15
tmac_drop_frms 0
tmac_bcst_frms 6
tmac_mcst_frms 6

rmac_fcs_err_frms 0
rmac_drop_frms 0
rmac_vld_bcst_frms 7
rmac_vld_mcst_frms 11
rmac_out_rng_len_err_frms 0
rmac_in_rng_len_err_frms 0
rmac_long_frms 0
