Packet Length greater than MTU
Hello,
I would appreciate some help with the following. We have 3 SUN X4450 servers, each of these servers talk to each other, one is an application server the other is a database server and the third is a web server. We also have numerous workstation and ACD connections.
When I snoop the application server I can see the following message a lot and I mean a lot
(warning) packet length greater than MTU in buffer offest
The NIC cards on the servers are all set as 1500 and the customer ensures us each router/switch/firewall has the same MTU.
When I snoop a particular packet I can see the Packet size as 1967 which based on the MTU doesn't seem possible. Also the do not fragment bit it set to 1.
So much questions are this;
1) Would there be a network device that is advertising an MTU greater than 1500
2) Would there be a problem with the Solaris server config, the e1000g.conf file hasn't be changed from the default
Any help would be greatly appreciated as finding where the issues lies is proving rather difficult.
Thanks,
Giles

SLIST(1) slist SLIST(1)
NAME
slist - Lists available NetWare Servers
SYNOPSIS
slist [ pattern ]
DESCRIPTION
slist lists all NetWare Servers available in your network.
If slist does not print to a tty, the decorative header line is not printed, so that you can count the servers on your network by doing
slist | wc -l
OPTIONS
pattern
pattern is used to list only servers whose names match the specified pattern. For a server to be listed, the pattern must match the full
server name. You can use wildcards for the pattern, but you must protect these wildcards from any command line expansion by quoting.
Case doesn't matter.
EXAMPLE
slist "I*"
or
slist "i*"
List all available Netware servers on your Network, that begin with an "I".
SEE ALSO
ncpmount(8), ncpumount(8), pqlist(1), nprint(1)
CREDITS
slist was written by Volker Lendecke (lendecke@math.uni-goettingen.de)
BUGS
slist works only in IPX environment, as it uses SAP to find first server and then Bindery to get list of servers.
