similar to: network interface up but no data

I've got a pair of identical CentOS 6.7 servers, with SuperMicro X8DTE-F motherboards, these have 2 each Intel 82574L ethernet ports. The eth0 ports are plugged in with 10' runs of brand new cat 5e cable to a Cisco Nexxus 9000 switch (provided by the data center). These servers keep coming up at 100baseT rather than gigE. I've swapped ports and cables with a different server,

CentOS 6.2......... Why do the physical interfaces report (correctly) that they're negotiated at 1000Mb/s, but when I `cat /proc/net/bonding/bond0` I get 100Mbps for the member interfaces, and when I ` mii-tool bond0` I get 10Mbps for the bond? ----------------------------------------------------------------------------------------- ethtool em1 Settings for em1: Supported ports: [

anyone know how to force network cards talk at gig speeds when all it wants to do is establish a connection at 100mbits root at host1 [/backup/cpbackup/daily]# mii-tool eth0: negotiated 100baseTx-FD, link ok eth1: negotiated 100baseTx-FD flow-control, link ok 01:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express (rev 11) Subsystem: Broadcom

Hi! Maybe, I found a bug of xen. My system: - domain0 - gentoo - xen-devel-3.0, kernel 2.6.12.5-r1 - domain1 - debian - kernel 2.6.12.5-r1 (2 interface: vif1.1 = eth0 (0.0.0.0), vif1.2 = eth1 (10.0.1.1 + gw 10.0.1.2)) Bridge: xen-br0 (config as 10.0.1.2) include (vif1.2, vif0.0) xen-br1 (config as 0.0.0.0) include (vif1.1, peth0) On server domain1 I use a pppoe server. If a send a pppoe request

How much of an impact can/does local network traffic have on call quality? Would opening large files on local servers affect call quality? We are running QoS on the router but that will only prioritize traffic in/out of the network.

I have just noticed this message in my kernel logs, reporting the possibility of an error with my memory. This would go a long way towards explaining the problems i''ve been having. This particular error is occuring when i''m not running xen so is obviously not something brought on by xen itself. The strange thing is that the NMI error is always followed by the TLAN: eth0: Adaptor

in dom0, how does one get and set the link information for a NIC? In a non-xen kernel, we could get this info by simply running: # ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes:

My system is: Intel CC820 motherboard (which supports PME# wake up for wake on LAN) 3com 3C905C which also supports wake on LAN via PME# Linux 5.5 The motherboard BIOS is later than one that reports an issue with WOL and this particular network card was fixed. But when I turn off the PC (shutdown or poweroff commands or front panel button), it cannot be restarted via WOL. The network light on

Dear All, I have an onboard Realtek RTL8111/8168B NIC. from lspci -vv : 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) It is detected, but why the speed is always 100Mbps, already change cable but still no luck. I use ethtool and from the output it seems that system know that this NIC support gigabit speed : ???????

We have an HP DL360 server with dual on-board Tigon3 ethernet cards. We are using eth0, eth1 is unused at the moment. Sometimes when the network interface is under heavy load, for example moving large file transfers over rsync or NFS, the network interface stops working and we lose all connection to the server. The only solution at this point is to jump on the console and restart the network

I want to check the speed like features of my Ethernet in dom0 and domUs. But in virtualized environment it gives strange output why is that so? how to check it otherwise? Non-virtualized FC11 [root@fasiha home]# ethtool eth0 Settings for eth0:     Supported ports: [ TP ]     Supported link modes:   10baseT/Half 10baseT/Full                             100baseT/Half 100baseT/Full

Hello everyone: Over the past few years I have been a happy samba user, running samba on Redhat / FC platforms. Recently I upgraded hardware, and Samba hasn't been performing well at all.. which makes me sad :-( The new hardware is Asus P5B board with a dual-core intel processor. This board has an onboard Realtek RTL8111/8168B gigabit ethernet controller, which was a hassle to setup.

I have the xensource 3.1.0 x86_64 tarball installed over a RHEL5 clone distribution. The "ethtool" utility only returns the following information: [root@fermigrid5 etc]# ethtool eth0 Settings for eth0: Link detected: yes [root@fermigrid5 etc]# Since I have no vanilla-installed rhel5 machines with which to compare, I am not sure if I am dealing with a bug in the ethtool (whose

Hello, Just did a fresh install of xen-4.0 and using the 2.6.31.13 dom0 kernel. I have 6 linux debian guests running, and on my host console i am getting these errors rolling pretty constantly. "Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet" I tried doing the ethtool -K eth0 tx off and same thing on peth0, using bridged mode for network config. Any tips?

Hi folks on debian stable I've a default samba file sharing config. Everything works perfectly (almost...) - samba version 3.6.6 >From linux and windows clients (wired and wifi too) when I (i.e. listen musics) often (one time every 4/5 minutes) networks suddenly collapse (for less one second) and immediately goes up. So I've an interrupt of broadcast (this happens also if I use rsync

Hi there, I'm having an odd problem where this NIC (cheap-o, yes I know) doesn't seem to work on FreeBSD correctly. I have the same cards (even revision models) in two win boxen and they work fine. 10baseT works but not 100baseT. With a normal NIC config, without explicitly setting the media to 10baseT, it will autosense as 100BaseT @ full-duplex, showing active. However I can't
