Im having problems changing a connection between a Cisco3560 and Cisco IBM Blade switch 3012 actually the configuration is access in Cisco 3560 and trunk int Cisco 3012 when i change the connection to trunk i lose conecctivity to the servers connected in the 3012, i have changed the access from vlan 1 to the respective vlan in the access port of the servers
View 5 RepliesI have 6 of these WS-CBS3012-IBM modules that need to be configured but I cannot access the USB console port. I was told I could just get any DB9- to- USB cable and that would work. I did buy a DB9-to-USB cable and it did not work. I looked up the installation guide for this module and it just said the console cable is DB9-to-USB but with no part number.
View 3 Replies View RelatedI have a 3560 8 port switch. Int gi0/9 is trunked to another switch downstream. When I try to configure int gi0/10 to trunk to a switch upstream the interface on the switch goes down and I have to either reboot the switch or plug directly into the switch and telnet into it to turn off trunking on the interface. When I configure trunking on the interface on the upstream switch that connects to this interface the same happens on that switch. The upstream switch is a 3750 with 12 sfp ports. Several interfaces are trunking to other switches from this switch. Spanning tree is not configured on the 3750 at all , and is not configured on either gi0/10 or gi0/9 on the 3560. I was consoled into the 3560 during a reboot after the interface went down, a message came up that said something like "Spanning Tree returning gigabit ethernet 10 to constant state" Why would I get this message if spanning tree is not enabled on the gig ports on either end of the trunk? There is no loop to require spanning tree to shut down an interface. I have several other 3560's configured as I would like to configure this switch and they are trunking without issue.

I dont understand what is the problem, actually i have added the command power inline never on the port and the problem is solved, but we haven´t changed configuration.
We have two Cisco switches with one 3560 and one 3750 we have created a new Vlan 4 with IP 10.1.3.x 255.255.255.0 - no shut then assigne to gi 2/0/46 on the 3560 Vlan 4 ip address 10.1.3.x 255.255.255.0 no shut then assign to FA0/45. All interfaces are up up along with the Vlan up up, we can ping the local IP address bu not able to pint the other switch.
View 2 Replies View RelatedI have a HP Procurve 5406 connected to a Cisco 3560 on a temporary cat5e connection and I have Mitel IP phones needing to go on the Cisco switch.Ive configured the HP Procurve port to TAGGING both VLAN 10 (data) and VLAN 20 (Voice). NO is selected for default VLAN 1.The Cisco is configured on the port with switchport encap dot1q and switchport mode trunk.
Ive configured an IP for interface VLAN 10 and i cannot ping it from across the network. The interfaces are up and happy. I have tried changing the VTP status from transparent to server (VTP pruning is off) ive tried setting allowed vlans 10,20. Still not a think. The worse thing is that i have a working Cisco switch with the HP procurve that i checked the config on and its the same! The only difference is that the media type is SX over SFP in that case.
p.s not that im at this stage yet but i initially configure the FastE ports as trunks with native vlans because i was using non-cisco phones. On a spare port i convigured the voice vlan 20 and i say on the mitel phone that it was looking on vlan20! I didnt expect that, i thought the Voice VLAN ID was carried on CDP enabled devices only.
my current network setup is like this.. a cisco 3560 is connected on an access port to an adjacent dlink stack. i want to enable trunking between the cisco and the dlink. what i know is that dlink doesnot support per vlan STP while dlink only run single instance of the STP.. how can i make the trunking possible without messing with the network.
the idea that i have is to run MSTP instance on the 3560 so that it appears as a single STP to the dlink switch and then all good. is there any other way to do that. if i just make both the adjacent ports on both the switches as trunk and connect them, will it cause any problem in terms of STP issues or convergence ?
If i replace a card of the same type in the same slot will I lose the configuration for that card or does it live in the backplane of the device?Is there any special command I need to run to replace the card or can i shutdown the 4507r-e and just swap out the blade?
View 3 Replies View RelatedWe have 12 Catalyst Blade Switches 3020 for HP running IOS Version 12.2(55)SE. In the configuration of these switches I see the statement shown below.
no spanning-tree vlan 34,45-55,70,600,643,840,843-850
The 12 blade switches are configured as VTP clients and running VTP V2. I did not configure the statement shown above. It appered by itself. And even if I delete it, it will reapper. (The blade switches are interconnected to two 6509s. The two 6509s are the STP root and VTP bridges. I configure Vlans and STP on the 6509s).
why the statement above appers on the blade switches 3020s?
I mean I use other Cisco switches such as 3750s and 3560s and I have never seen the statement above appear by itself.
Looking at the specs for WS-X6704-10GE, it shows the port buffers at 16M per port. This doesn't seem like very much for a 10G port. Is this upgradable or related to how much RAM is in the blade?

some of our switches have the switchport mode trunk command configured between the 3750 switches but other 3750 switches connected to our 6509 core switch do not have the switchport mode trunk command to permit Vlans from going across the swtiches instead it has an ip address and says no switchport what is the difference between does two. Is trunking used only for Layer 2 and L3 is used to route interface vlans?

I am very new at this, but we have a 2801 router running 12.4, a 3560 that acts as the "Core" switch, and a bunch of remote 2960G's that connect via fiber to different buildings.
I am tasked to VLAN this network to reduce broadcast traffic. I started by setting up a VLAN 169 on the "3560" named the VTP domain, changed to version 2, and no password. THe Core switch and remote switch can share the VTP info, I HAD the Router seeing it too (able to ping 192.168.169.1) until I changed the "Domain" and "VTP Version"
The switches see each other fine, my problem is the Router sub interface 0/0.169 I cannot get to see the VTP domain. I imagine because I don't have a "Trunk port" set on the Router, but the option is not there. Meaning I cannot do a "switchport mode trunk" on it. The only thing I see is to make it:
TCRouter(config-subif)#encapsulation dot1Q 169 native
But, my "int fas 0/0" is used now as the main interface for our "only" network 192.168.0.0, do I need to turn this over to a subinterface and make it "Native" then the difference of the subinterfaces will advertise? Here is some of my conf:
Core SW:
TCCoreSW#sh vtp status
VTP Version : running VTP2

We purchased two new 4948 with two 10GE uplink ports and upgraded the devices to run IOS 15. My 6506 is running Sup 720 with s77233-adventerprisek0_wan-mz.122-33.SXI9. Currently we have 4948's connected to the same 6506's with no problems. Today I tried to add the new switches with new IOS and it caused of of my 6506 core switches to failover. I can't explain why because it was close to start of business and couldn't do much troubleshooting.
Currently we have four 4948 (running IOS 12.2(14) switches running Layer2 connecting dually to each of the two 6506 cores via 10GE fiber uplinks. I tried to add two more to the scenario, again running layer2 and dual-honing them to each of te 6506 switches. there are two 6506 core switches and they run HSRP and spanning tree is manually set to give priority to even vlans on one 6506 and odds on the other 6506. Also the new switches I tried to add did had rootguard applied as well as the uplinks.
We have to get this working and have no test environment to work with. We need to do this late this evening after close of business.
On another note, I have had problems upgrading some of my older 4948's to IOS 15. I followed Cisco's suggestion and upgraded the EPROM first and then the IOS upgrade took on three of the switches that were ordered rather recently. The four that were ordered in one batch will not take the upgrade even following Cisco's instruction and lots of other tricks. Nothing works. Having problems with IOS 15, in general?
I currently have 5 3750s connected via Stackwise. This stack is connected back to my core (6509s) via fiber (1Gig to Core1 & 1Gig to Core2). I want to move the 5th 3750 to another closet due to an addition of a new patch panel. Due to max length of 10 ft. for stackwise, my plan is to connect this 5th switch back to the stack using trunked fiber ports, with them being an etherchannel (2Gig). Also plan to use single fiber port form 2 different switches in the stack to provide some redundancy for the 5th switch. Should I be alert of any issues with this connection design? Do I need to properly remove the 5th switch from the stack using, no sw 5 provison sw-model or can I just disconnect stackwise and connect back with fiber?

We're trying to configure our Cisco 4507 (Supervisor Engine IV) to allow a new Dell server with a pair of Broadcom 5708 GigE NIC's to aggregate its NIC's to give us a 2gbps link to the switch.
So far we seem to have got the team and LACP up and enabled, but the adaptor that the Broadcom Admin Util creates for the team is only showing a 1gbps connection where I would have expected it to show as 2gbps.
The individual NICs show as connected at 1gbps. We're not Cisco experts so are struggling on how to get the 2 NICs to aggregate.
On the server side we've done nothing other than create a team using 802.3ad LINk Aggregation using LACP.
This is what I think the relevent output from "sho conf" is, more available if needed.

Imagine I am designing a small network with a C2900 router running OSPF and in the future BGP with service provider. Please see attached diagram.The router is connected to (2) C3750 Layer 3 distribution switches. Then one C3560 layer 2 switch to serve future IP phone users and desktops.
Question:
a)If I connect the router interface to the (2) 3750 switches, if I make the router interface fa0/0 and fa0/1 as a trunk to accomodate VLAN 200 and other future VLANs, don't I have a problem with overlapping networks between router interface fa0/0 and fa0/1?
b)Alternatively, I could make the Router1 fa0/0 and fa0/1 configured with IP addresses and advertised in OSPF. Then the SW1 fa0/24 and and SW2 fa0/24 I could make as 'no switchport and create a routed interface port' with IP addresses, also running OSPF. Question is, from a scalable design perspectie, would you create 2 management networks and use those when assigning the IP addresses for Router1 fa0/1 and fa0/2? Because again Router1 fa0/1 and fa0/2 obviously need to be placed on different networks to avoid overlapping. So my question is more about proper network planning design to make this scalable to accomodate future VLANs in the future.Using trunks between the Router1 and SW1 option:
Router1
int fa0/0
description connection to SW1
no ip add
int fa0/0.200
[code]....
have setup a small lab as per CBTNuggets. Everything was going well until I introduced a second switch to create a trunk. Now I cannot ping between my two switches. Both show operational mode as down:
SWITCH1#show interfaces f0/12 switchport
Name: Fa0/12
Switchport: Enabled
Administrative Mode: trunk
Operational Mode: down
Administrative Trunking Encapsulation: dot1q
[code]....
I have tried to allow all vlans or vlan 1 specifically and the output of the above doesn't seem to change. I am wondering if there is something in the config-register that is preventing trunking, but I don't really know enough yet!
The output of my second switch is identical to this one, the only difference is that I have it configured as a vtp client.
We have been facing a problem at my company ! We have a Cisco Router 1921 with one HWIC-4ESW in trunking with a RuggedCom switch RSG2100.When I use the GigabitEthernet port to make a trunk, I create 2 sub-interfaces (one for each Vlan) and configure the Port on Switch as Trunk, the inter-VLan routing works with no problem.But now I need to use this configuration using the HWIC-4ESW on Router, and I can't do this work. I try creat interface Vlan for each vlan, and try creating the VLans at Router Vlans database, but no way. At router I enter in interface and try to do the switchport trunk command to add a Vlan, but doesn't work.
