I have a Allied Telesyn AT-GS950 16 port switch.
All hosts&router have rtl8139 NICs.
OS : Slackware linux 12.1.
I use a switch with vlan technique to separate my network to some segment.
here my plan:
router eth0 ---> switch port 1
switch port 5 <--- eth0 host A
switch port 6 <--- eth0 host B
in eth0 of router, I make two vlan :
host A :
host B :
Arrange vlan configuration in switch :
ping result to both host A and host B from router gave same result : Destination Host Unreachable
ping command :
Please help, there's maybe I have wrong concept about vlan configuration?
Thank you very much.
Regards,
Denny
All config seems to be ok. Check ping from host to router (in same network, 172.16.5.2 -> 172.16.5.1 etc). Check running router process on router. And check trunk mode on AT switch - it must be 802.1q (dot1q).
Additionaly try to disable firewall on router, if you use that
hi,
i tried to configure an VLAN interface on my SF280 based on the documentation on docs.sun.com

I do have 2 different segment network which different platform on each segment. E.g. 20 segment, Windows OS can talk to Unix OS and 21 segment practice same rule. Further more, Windows OS from 20 segment can talk to 21 segment other OS but only the UNIX OS in 20 segment fail to talk to 21 segment.... (3 Replies)
Hi all,
so server: FreeBSD 7.0 release,
interfaces on it DLINK DGE-528T with support of vlans :))
so first interface looks to LAN second to ISP.
I created vlan1 with id 1 and gave to it ip address and plug it in
tagged port of swith for vlan 1. so client from vlan1 reaches the server.

For this purpose I'm configuring 2 Linux system as a switch and connect 4 host to them. Then a router is added to scenario.
The configuration of the switches is:

Hi,
Is it possible to VLAN tag with a ce interface on Solaris 9? Link speed is gb.
ce:0:ce0:link_speed 1000
I have a ce0 interface I would need to have access to another VLAN as well as the one it's currently on.
What commands would I need to run?
Thanks.;) (2 Replies)
We have two hosts in same vlan with same route rules.
One of them is not able to connect to an outside IP while in another I get "failed: Connection timed out" while testing the connectivity through netcat.
I have tried mtr /traceroute and it gives me the same results.
Is there a netcat... (1 Reply)

Hi Folks,
I am currently moving systems to a new environment, with some changes to the network requirements on the systems.
One of these changes is moving from just standard IPMP to using IPMP on top of a VLAN, I have used VLAN tagging befor without issue - however not with IPMP.
What I... (2 Replies)

ibportstate
IBPORTSTATE(8) OpenIB Diagnostics IBPORTSTATE(8)NAME
ibportstate - handle port (physical) state and link speed of an InfiniBand port
SYNOPSIS
ibportstate [-d(ebug)] [-e(rr_show)] [-v(erbose)] [-D(irect)] [-G(uid)] [-s smlid] [-V(ersion)] [-C ca_name] [-P ca_port] [-t(imeout) time-
out_ms] [-h(elp)] <dest dr_path|lid|guid> <portnum> [<op>]
DESCRIPTION
ibportstate allows the port state and port physical state of an IB port to be queried (in addition to link width and speed being validated
relative to the peer port when the port queried is a switch port), or a switch port to be disabled, enabled, or reset. It also allows the
link speed enabled on any IB port to be adjusted.
OPTIONS
op Port operations allowed
supported ops: enable, disable, reset, speed, query
Default is query
ops enable, disable, and reset are only allowed on switch ports
(An error is indicated if attempted on CA or router ports)
speed op is allowed on any port
speed values are legal values for PortInfo:LinkSpeedEnabled
(An error is indicated if PortInfo:LinkSpeedSupported does not support
this setting)
(NOTE: Speed changes are not effected until the port goes through
link renegotiation)
query also validates port characteristics (link width and speed)
based on the peer port. This checking is done when the port
queried is a switch port as it relies on combined routing
(an initial LID route with directed routing to the peer) which
can only be done on a switch. This peer port validation feature
of query op requires LID routing to be functioning in the subnet.
COMMON OPTIONS
Most OpenIB diagnostics take the following common flags. The exact list of supported flags per utility can be found in the usage message
and can be shown using the util_name -h syntax.
# Debugging flags
-d raise the IB debugging level.
May be used several times (-ddd or -d -d -d).
-e show send and receive errors (timeouts and others)
-h show the usage message
-v increase the application verbosity level.
May be used several times (-vv or -v -v -v)
-V show the version info.
# Addressing flags
-D use directed path address arguments. The path
is a comma separated list of out ports.
Examples:
"0" # self port
"0,1,2,1,4" # out via port 1, then 2, ...
-G use GUID address argument. In most cases, it is the Port GUID.
Example:
"0x08f1040023"
-s <smlid> use 'smlid' as the target lid for SM/SA queries.
# Other common flags:
-C <ca_name> use the specified ca_name.
-P <ca_port> use the specified ca_port.
-t <timeout_ms> override the default timeout for the solicited mads.
Multiple CA/Multiple Port Support
When no IB device or port is specified, the port to use is selected by the following criteria:
1. the first port that is ACTIVE.
2. if not found, the first port that is UP (physical link up).
If a port and/or CA name is specified, the user request is attempted to be fulfilled, and will fail if it is not possible.
EXAMPLES
ibportstate 3 1 disable # by lid
ibportstate -G 0x2C9000100D051 1 enable # by guid
ibportstate -D 0 1 # (query) by direct route
ibportstate 3 1 reset # by lid
ibportstate 3 1 speed 1 # by lid
