VLAN prioritization for SAN traffic

I have a stack of 3750's running two VLANs, one for NFS traffic (id 130) and one for iSCSI traffic (id 150). I have jumbo framing (MTU 9000) on VLAN 150. I'd like to try prioritizing the iSCSI traffic using 802.1p. Can anyone point me to some configuration help? Does anyone have any thoughts or experiences with this idea? Thanks!

The MDS GE/iSCSI interface can set the DSCP value on outbound IP packets, but that is in the IP header (layer 3). From what I recall, the 802.1p bits are in the Layer 2 field between the MAC addresses and the Ethernet type, and from what I understand, the MDS does not provide any marking at that level.
You could mark via 802.1p inbound on the Ethernet Switch that the MDS GE port is attached to, but not directly out of the MDS GE port.
If you are interested in marking iSCSI using DSCP, here is web page describing how you set the iSCSI interface for the desired DSCP value.
Hope this helps,
Mike

Yes, I do.
laugh - I was temped to stop with the above, as it directly answers your question, but I assume you want to know how.
In principle, you recognize the VoIP traffic as being different from data traffic and provide it "special" egress treatment. Normally you would enable QoS, and for egress, enable PQ, direct VoIP bearer traffic to that queue. You might also direct VoIP signalling traffic to a queue that insures it's not unduly delayed or dropped. You might also set rate caps on ingress VoIP traffic.
Recognition of VoIP traffic can be done in different ways. Your phones might support L2 CoS or L3 ToS marking, your switch might "analyze" ingress traffic, your switch might trust a Cisco VoIP phone, your switch and VoIP phones might use a dedicated VLAN. Basically, there's lots of variables dealing with ingress.
Unfortunately, you've provided insufficient information for specific recommendations.
PS:
BTW, your 2960 might also support auto-QoS, which may, or may not, be all you need to enable.

JumboFrames on cisco3750g for iSCSI traffic

Hello Communality,
I need you help!
here is the goal: connect SAN and vmware ESXi by iSCSI via cisco3750g.
on cisco I'm using a separated vlan for iSCSI traffic.
So after turning on the JumboFrames on cisco ( system mtu jumbo 9000 > reload) I was trying to test it using PING command from the switch without success :-(

Hello
Does the interface need to be an access port or trunk?

I'm not 100% certain, but I believe FastSwitching and CEF switching apply to unicast, not multicast. Your "IP mroute-cache" command enables/disables fast multicast switching.
On a 3750, switching should be hardware based, for unicast and multicast, unless TCAM resources are insufficient. If hardware switching falls back to non-hardware switching, you'll likely find process vs. Fast vs. CEF vs. multicast doesn't matter, all too slow.

VLAN tagging for Desktops

I have a test VDI 3.1.1 system set up and I have to say, I'm quite impressed. In about a day, I was able to serve Windows 7 desktops, something we can't do with our current VMware View setup. One apparent limitation I have run into, however, is 802.1q VLAN tagging support for Desktop NICs. I have created a 2-way aggregate on nxge0 and nxge1. The portchannel these are connected to is set up for 802.1q tagging, and Solaris is plumbed with aggr13001 to tag its packets with VLAN 13, for example. However, traffic from Desktops is not so tagged, so its packets go nowhere. Is there any way to define a VLAN for a given Desktop Pool? This is important for us, as we tend to keep server systems on campus-only subnets, while desktops get Internet-routed addresses.
Thanks,
Charles

Aggregation shouldn't have any adverse effect here. You need to configure VDI to use the correct VLANs on a per Pools basis. In the VDI Manager first navigate to the Desktop Provider -> Networks tab and 'Refresh' the networks. This will scan all VirtualBox hosts in the provider for currently plumbed interfaces, each of which will be listed by their subnet.
After all networks are detected navigate to the Pool -> Settings tab and select 'Host Networking' followed by the required subnet(s). The primary subnet listed here is used for RDP connections.

VLAN Setup for VMware

I'm new to creating VLANs on a Cisco switch, and I'm trying to create VLANs using the SG 300-10 for a VMware environment. I'd like to use Virtual Switch Tagging on the ESX hosts, so I can use many VLANs over few physical NICs. Plus using VST, I can just specify the VLAN ID (setup on the physical switch), on the port group for each VLAN.
I've changed the SG 300 to layer 3, as I'd like inter-routing between my VLANs. This is the type of setup I'm looking for:-
VLAN1 - Default
VLAN 10 (192.168.10.1) to 20 (192.168.20.1) linked to ports GE3 & GE4. I've connected port GE3 to ESX1 (vmnic2) and port GE4 to ESX2 (vmnic2)
The problem is when I check my physical network adapters (i.e. vmnic2) in vSphere, the IP Ranges for observed traffic in every VLAN specified for the configured port are not showing (i.e. networks 192.168.10.1 to 192.168.20.1)
I have attached screen captures of all my setup & configuration so far, I'm obviously making a mistake...
Could someone please advise what I'm missing?
Thank you

Administration port - network channel for admin traffic

I am trying to configure a separate channel for Administration traffic on weblogic. I followed the oracle docos and configured the SSL, domain wide admin port, server listen address, ‘admin’ channel.
The issue is admin traffic in not happening through the newly created channel.
L2 network is not getting used. I can’t see any activity in the monitoring tab of new Channel. Also the netstat is showing that the port 9101/9102 is getting used on the 192.168.100.218 and not on 10.254.252.849.
I also tried by setting up the newly created channel weight as 51, but no luck.
Is JMX connectivity related to admin channel?
Any help is highly appreciated. Thanks.

Hi
For first question the answer is no. With the administration port, you enable the SSL between the admin server and Node manager-managed Servers. You can still use the web console.
For teh second question, you can use ANT or can use the WLS Scripting ..you can get more details in dev2dev.bea.com

Is Cisco Nexus 5596UP support vlan base Policing and traffic shaping on code NX OS version: 5.1(3)N1(1)

Is Cisco Nexus 5596UP support vlan base Policing and traffic shaping on code NX OS version: 5.1(3)N1(1)
where i couldn't see any police command under the policy map

I have tested this issue on another 5548UP with L3 running the same NX-OS version and get the same problem. Show CDP from the switch is not discovering devices, but the neightbors can see the 5K in question. Reboot sometimes will fix it, but not always. I suspect a problem with the software since that doesn't happen in NX-OS 5.2. The one I am using is
Software
BIOS:      version 3.6.0
loader:    version N/A
kickstart: version 5.1(3)N2(1)
system:    version 5.1(3)N2(1)

Outbound PAT for SMTP traffic

Cisco ASA 5505, Software 8.0(3)
ASA IP: xxx.xxx.xxx.yy4/29
This is part of my ASA config that ensures PAT for incomming SMTP traffic:
access-list acl_inbound_outside extended permit tcp any host xxx.xxx.xxx.yy7 eq smtp
nat-control
global (outside) 1 interface
nat (inside) 0 access-list acl_no_nat_inside
nat (inside) 1 0.0.0.0 0.0.0.0
static (inside,outside) tcp xxx.xxx.xxx.yy7 ftp 172.27.1.1 smtp netmask 255.255.255.255
access-group acl_inbound_outside in interface outside
This ensures SMTP traffic to xxx.xxx.xxx.yy7 reach my SMTP server.
But outgoing SMTP traffic is from xxx.xxx.xxx.yy4 (WAN IP of ASA).
How can I set up that ONLY SMTP traffic from 172.27.1.1 is PATed behind IP xxx.xxx.xxx.yy7 and other traffic from 172.27.1.1 will be NATed to
xxx.xxx.xxx.yy4?

Hi,
It seems that there is either a typo or mistake in the configuration above.
You are forwarding "ftp" port to "smtp" port
Shouldnt it be
static (inside,outside) tcp xxx.xxx.xxx.yy7 smtp 172.27.1.1 smtp netmask 255.255.255.255
So in addition to forwarding the "smtp" port you also want all outgoing "smtp" traffic from this single host/server to use the public IP address xxx.xxx.xxx.yy7
Then you can configure this
access-list SMTP-POLICYPAT remark Policy PAT for SMTP traffic
access-list SMTP-POLICYPAT permit tcp host 172.27.1.1 any eq smtp
global (outside) 25 xxx.xxx.xxx.yy7
nat (inside) 25 access-list SMTP-POLICYPAT
Hope this helps

How does Websense expect your source IPs in the tunnel? 192.168.8.0 0.0.3.255 or PAT'ed 216.222.208.101 ?

Can i use 3750 for SAN

hi.
my question is can i use the switch 3750 for SAN?? and what must i do to make it right ??
thnx

The Catalyst 3750 cannot be used for fibre channel SANs at this time. It can be used in conjunction with the MDS9500 switch with an IP storage services module (IPS module) or an SN5428-2 storage router to connect hosts to storage using iSCSI or geographically separate switches using FCIP. The MDS9500 and SN5428-2 have gigabit Ethernet interfaces that could be connected to a 3750 with GigE.

Which network is Oracle using for RAC traffic ? where you will get info ? ?

Hi,
I am using two node RAC on Oracle 10g R2 (10.2.0.3.0) version on SUN Solaris 10 . I want to know "Which network is Oracle using for RAC traffic ? where you will get info "
--Kumar

Hi Kumar,
In 10g, you can query x$ksxpia. If the cluster_interconnect information is stored in OCR (default), you will get
SQL> select INST_ID,PUB_KSXPIA,PICKED_KSXPIA, NAME_KSXPIA,IP_KSXPIA from x$ksxpia;
If you specified the cluster_interconnects parameter in your init.ora:
Columns to look in : INST_ID P PICK NAME_KSXPIA IP_KSXPIA
And also you can use 'oradebug ipc' to see which interconnects the database is using:
SQL> oradebug setmypid
SQL> oradebug ipc
Hope it helps...
Thanks

Cascade Catalyst 3560 switch for loaded traffic

I have a layer 3 Catalyst switch 3560 with 24 FE interfaces.
I need to pump traffic from traffic generator into port 1 and propagate it to other ports; the last port will be connected back to the traffic generator.
I suppose that I need to cascade some of the switchports but how do I configure the catalyst switch for this setup? Is it making use of routed port and static routing?

Hi Ankur,
Thanks for the reply.
The traffic generator are layer 3 interfaces which I can assign IP address.
You mentioned that I do not need any routing, but I require traffic coming from the traffic generator(e.g FE1) going into switchport 1 to traverse through the rest of the switchports before exiting from the last switchport back to the traffic generator(e.g FE2). Therefore, I need advice on how to setup the catalyst switch to achieve this.If I assign ip address for this traffic to end at the traffic generator-FE2, the generated traffic will enter the switch at switchport 1 and directly exit from the last switchport without any traversing done. Btw, do I need to cascade my switch with cross cable in this aspect?
Thanks in advance for your advice.
Regards,
Raymond
