New packet loss issue
I've submitted this as a Sun case, but I thought I'd post here as well
to see if anyone else has experienced this problem. Any ideas?
The server is an x4100 M2 running Solaris 10 11/06 x86. Patches were
current as of 4/9/2007, including a reconfig reboot at that time.
Yesterday, the server was rebooted and afterwards the packet loss was
noticed immediately. Note that as part of troubleshooting this
problem, I've brought the patches up to date as of yesterday,
performed a reconfig reboot, as well as performing a cold boot (with
power cables completely removed).
...Reapeatable packet loss on ulip interface over Solaris TCP on 100Mbps
I use VxSim with ulip over Solaris8.
Whenever the gap between 2 packets < 10usec -
The second received packet does not arrive to ulip interface.
This cause a very slow TCP connection.
On 10BaseT it never happens (probably because the inter packet gap > 10 usec).
Did anyone encountered this problem?
Can anybody help me in the following subject?
Situation 1. Router 1 (2500 series) have 2 Serial Interface connected
to 2 Branches. Loopback Interface is also configured for the Router &
is running OSPF as the Routing Protocol. Does the Loopback Interface
have any role to play if both the Serial Interfaces goes down(Line

I'm running a slave kerberos KDC on my OS X laptop. I need to access
the KDC when the laptop is disconnected from any network, but the KDC
doesn't bind to the loopback interface, and I can't seem to setup a
dummy interface in OS X. OS X shuts down any interface on which it
can't detect a link. How can I force the KDC to bind to the loopback

Is it possible to create many loopback interfaces (as in Cisco
routers) and get different statistics for these interfaces ?
...problem with ethernet loopback test using loopback plug/stub: receiving socket not seeing packet.
we are writing socket application to send UDP packets out from eth1
and loop it back to
the same interface using loopback stub to verify the hardware without
devices/ports. The sending and receiving port are the same.
our target machine has eth0 configured as 15.6.xx.xx and eth1
configured as 188.8.131.52.
the listening socket is listing on all ip.
When we looked at the packet in the tx code of the driver, we have
observed that the packet passed down from the ip stack has the same
MAC address for both source and destination. Also when packet is
returning, its ip source and...loopback interface / VPN
I set up my router 877 to use EzVPN/xauth to connect to the office
Whenever it succeeds in making a VPN connection ( for testing, I do it
many times ) the config shows another line of interface loopbackN.
Right now it shows :
ip address 192.168.235.114 255.255.255.255
ip address 192.168.235.118 255.255.255.255
ip address 192.168.235.119 255.255.255.255
ip address 192.168.235.131 255.255.255.255
Can this cause any problem if I just let them there ? Or do I have to
clear the old ones ? In the...some commands about loss packet
On the c 4500 is command:
show platform cpu packet statistics all
Now i have c 4006 and i can't find this or similar command. I'd like to now
about loss packet when the cpu is overhead or near overhead and when the
proces packet forwardig is big how many packets is droped. The command sh
proc cpu is not enough, i think...
If you are running CEF, then see
sh...50% packet loss ?
What does it meen when my ping reply is !.!.!.!.!.!.!. for one IP-address.
In LAN the ping reply is !!!!!!!! but from another network only every other
packet is comming back.
Check for static route to non-existing or dead gateway. For example, if you
have two static routes with the same metrics to the same destination, router
will try to do a load-balancing between gateways, and if one is down, you
will get every other packet lost.
