My entire switching network is enabled RSTP and I have purchased a new cisco 3560X series switch and I have not found RSTP feature in my switch.Is it available if I change the image? will cisco switches supports RSTP?

View 3 Replies View RelatedI acquired a 3560X-24P-L Switch which I wanted to use at our datacenter. However, I need a switch that supports OSPF. It came with a Universal IOS but there was no "Router" command under conf t. I downloaded and applied the latest "IP Base" IOS, but still no Router OSPF. Based on the matrix here > [URL] I thought "IP Base" supported OSPF, but what exactly is "OSPF for routed access" ? Do I actually need an "IP Services" IOS? From my download options, I do not see an IP Services IOS for the 3560X-24P-L so I'm left to assume that the switch does not support L3 / OSPF. So my question is this particular switch supports L3 / OSPF and what is Universal IOS?
View 5 Replies View RelatedI have Cisco 3560X L3 switch and i need to configure DHCP on this switch. I have already configured below mentioned VLANs
VLAN 10 - 192.168.8.254 (USER VLAN)
VLAN 20 - 192.168.152.254 (REMOTE & VPN USERS VLAN)
VLAN 30 - 192.168.0.254 (SERVER VLAN)
After configuring DHCP, all the users needs to get IP from USER VLAN and all the servers should get IP from SERVER VLAN. If yes, what are the steps as I am very new in this kind of configuration.
I am trying to join a Cisco Catalyst 3560X-24T-L to an existing VTP domain, my question is what configurations should I do to this switch?I have already gave it a hostname, setup passwords, enabled telnet, created a management address on port g0/24.I would like it to be on VLAN 13, is this done from my server switch, or done on the new switch?
View 10 Replies View RelatedI haven't worked with infrastructure much lately but planning on replacing a Dell switch used for a small iSCSI SAN with a Cisco 3560x. Switch is sstorage ONLY, network handled through different switches. I believe I want to disable spanning tree and configure trunking for the 4 GB ports connected to the storage array. The switch is providing connectivity to SAN via multiple GB connections and then also multiple GB connections to 3 Vmware hosts.Can you look over the changes I made to config below and let me know if I am on the right track.
I also plan to add a second switch later with the 10GB modules to interconnect for redundancy (but not worried about that part for now). I do not plan on using jumbo frames.
Here are my questions
1) Is the best way to globally disable spanning tree for the switch?
2) Did I trunk the ports correctly below?
3) Should I apply any specific SmartRoles to the 4 SAN NICs (GE1-4) or to host NICs (GE13-20)?
4) Anything additional I should do to handle iSCSI data?
Here is a copy of the config so far with my changes marked in RED.

I have one 4506E switch working in Lan setup as a core switch with WS-X45-SUP6L-E running ipbase IOS 12.2(54)SG1. Each time after reload the switch we found that the clock is getting reset ( time is getting changed ) where as day, date & year is unchanged.
View 2 Replies View RelatedCurrently I'm with a pure Cisco shop, running every LAN Switched infrastructure (even in the HQ datacenter) with PVST+, I'm noticing in the documentation I've read and labs I've created that RSTP is... great, and I've observed that even the uplinkfast functionality seems to be build in by just enabling rapid-pvst. Of course I'll propose a migration plan, document the network, diagram it entirely and provide effective steps to implement the change, but that's assumed from any get'go.

Or do you have RSTP running in now-a-days switches?
I need to setup a layer 2 network consisting of 14 switches interconnected in a ring. Obviously, the design of 14 switches in a ring network is dumb, not here to debate that. Unfortunately, it HAS to be a ring. I've been researching the best way to configure RSTP for this. From everything I've read all I really need to do is configure Primary/Secondary root bridge in the center, and change the Maximum Age field to at least 16 seconds? From what I've read you want a minimum of 3 second buffer + 1 second for each hop due to message age being added by each switch hop?

I have a 7609 with two LAG groups (Etherchannel not LACP) going to two separate devices that DO NOT participate in spanning-tree (Occam gear if you must know). I'm running 802.1w across the LAG groups but the convergence time is terrible! In essence, the 7609 is running spanning tree against itself (between the two blades). What can I do to fix my configuration?
If I disable the ports on the equipment connected to g1/17 & g1/18, it takes ~30 seconds for spanning tree to start forwarding on g2/17 & g2/18.When I bring the ports back up on the other side of g1/17 & g1/18 which are in a lag group, g2/17 & g2/18 immediately go into block mode while g1/17 & g1/18 start learning for another ~30 seconds!!

I have two Cisco 3560x switches running IPBase on different sites joined by a 1gbps connection with routed ports. I have video data totalling 80mbps in site A that is crucial to arrive at Site B regardless of any other traffic on the network.
What I would ideally like to do is reserve 100mbps on the link from A->B which is only allowed to be used for this traffic. The traffic starts in a subnet of its own and finishes in a subnet of its own (i.e. only the video traffic is in the VLAN on each switch with data and voice in different subnets).
I have Cisco Prime 4.2 and several 3560X switches. I want to enable energywise on then but after doing the Readiness Assessment they apper like "Hardware not Capable". As far as I know the 3560X do support energywise.
The switches details:
WS-C3560X-48T-S running IOS 15.0(1)SE3 (C3560E-UNIVERSALK9-M).
Does those switches do not support energywise?
I'm planning to use 2 3560X (access switch) on two different locations connected over two 2921 routers in small ring. 3560Xs are directly connected via fiber. Each 3560X is conected to its own 2921, and 2921s are connected together with GRE over IPSec. So they are creating ring.I'm planning to use small area 0 in this scenario. There are less then 200 routes in the network. Will 12.2(55) IP Base on 3560X support this scenario or I will need IP Services image? "OSPF for routed access" is still little vague to me, there are only tipical case study scenarios.

View 5 Replies View RelatedI have seen a similar post here from last year about a 10/half connection, but this is different. I have a provider using a 2950 switch (they left CDP on so we can see it). And we have to be set to 10/full to make this connection (as you know 10/half connected here would be or is horrible). I have had this connection running on my 2921 router w/o issue but when I connect it to my 3560X, then I get no link light (shows down/down, not connected).
What else to know about what has been tried: Connecting link to switch with switch set to auto/auto (sp/dup). Speed is 10 (as it should be) but of course w/o the other side pulsing the voltage to know what to auto to, it defaults to half so this is unacceptabel, but, I do get a link light and can pass traffic, it's just a horrible experience.
Also tried the same setting speed and duplex vs. auto disco speed and duplex on other ports of the switch, no difference, same results. Also different patch cables, same results.
My current work around is to connect the providers 2950 (10/full) to my 2921 router @ (10/full) with a BVI to another port on the router which continues on to my 3560X at 1G/full. And this works just fine. Here's more info from my 3560X and the providers 2950:
