Attempting to trunk an Avaya POE switch to a Cisco 3750X switch. Here's the Cisco port config: [code]
Cannot PING Avaya switch at 10.89.0.5. I have Cisco switches at .1,.2 and .3. I can PING those and access them. Any additional config needed on Cisco trunk port?
I'm having a problem with some new gear and can't seem to figure it out. I have a 3750X-48P-S with a C3KX-10G-NM using SFP-10G-LR transceivers and I'm trying to trunk that with a 6509 that has a X2-10G-LR transceiver over single mode fiber. This is not working. Cisco TAC says the SFP+'s that we just got brand new are both bad and we need to order new ones. I find that hard to believe but who knows.
The switch recognized the module and I tested all 4 ports in gigabit mode using GLC-SX-MM transceivers, all worked great. I have the SFP+'s in tengig1/1/1 and 1/1/2 as they should be. There are no other SFP's in the module either.
When I do a sho int tengig1/1/1 and 1/1/2 the media type doesn't show the transceiver that is installed like it does for the GLC-SX-MM ones. Maybe it's not supposed to or maybe it just doesn't recognize them and it's a hardware issue.
how we can configured 3560 for Avaya IP phone ? , we would link to use voice and data connect to the same port
View 1 Replies View RelatedI'm introducing a Cisco 3750 switch into a Avaya environment for testing/lab. I'm concerned about any STP, VTP problems I might create as I'm going to give a address on the Management VLAN and connect it to a trunk port on a ERS5520 Avaya. I've set the switch to transparent mode and the VTP revision is set to 0. I've checked the STP priority but it doesn't give any - there is no output because it is not connected. I wouldn't be so concerned but, I'm not sure if any config has been on it before.Also, is there any way for me to see the STP prioroity without having it connected?
View 10 Replies View RelatedWe have a pair of ASA 5585X firewalls that need to connect to a pair of Avaya VSP9000 switches. The Cisco docs refer to doing spanned etherchannel with a Cat 6500 switch using VSS or a Nexus switch using VPC. Does spanned etherchannel work with non Cisco switches or is this proprietary? The etherchannel on the ASA is setup using LACP. Here's applicable configuration:
interface TenGigabitEthernet0/6
channel-group 2 mode active vss-id 1
!
interface TenGigabitEthernet0/7
channel-group 2 mode active vss-id 2

interface Port-channel2

Since Avaya phones do not run CDP, how does the phone know which DHCP pool to pull from to get its IP address if the PC is connected to the phone.
Let's say I have a interface config like this
interface gigabitethernet1/0/1
cisco3750(config-if)#switchport mode trunk
cisco3750(config-if)#switchport access vlan 126
[code]....
And two DHCP scopes configured on the switch. What keeps the phone from pulling from the wrong scope?
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?
View 2 Replies View RelatedI 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
Configuration Revision: 8
Maximum VLANs supported locally : 1005

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?

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.

I am trying to trunk between a 3Com 4800g and a Cisco 3500xl. I can get the a PC that connects to a vlan 1 port on thecisco switch to connect to the 3com switch and get connectivity. However, I cannot get anthing on the cisco switch that is on vlan 2 to connect and get dhcp. I am not a 3com guy, so I am not familiar with the command and configs.We have 2 vlans on both switches: Vlan 1 is Admin and Vlan 2 is Student.

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

I 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 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.
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 Replies View RelatedWe 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.
View 4 Replies View RelatedIf you have a router with multiple direct vanilla FE (non trunked) interfaces on a switch trying to send QOS tagged packets to a wifi bridge several switches away does the trunking in the switched infrastructure mess with the qos tags if no qos is configured on the switches.
Does it depend on the switch? We have new 2960's running 12.2 and a few older 2950's running 12.1
I've run into an issue with this type switch. I've a 2611xm router connected to a C2924-XL switch ((C2900XL-C3H2S-M), Version 12.0(5)WC17) Basically i configured the router as a RoTS with two sub interfaces setup with encapsulation dot1q.

I 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.
Do the cisco 4503 switches support virtual clustering feature ? I have a requirement where switch ports on two different 4503 switches need to combined in the same Link aggregation group . This is needed because the firewall notes say that the aggregated interfaces need to be conected to a single switch and combined in the same LAG . So according to the diagram below , the interfaces marked RED need to be in the same LAG in the switches , same for the interfaces marked BLUE . I have done the same setup using Juniper switches where it uses VIRTUAL CLUSTERING to group the different switch ports in the same LAG.

View 2 Replies View RelatedI have a stack of 2 x 3750X switches these are running 12.2(55)SE5. I needed to add some static IP routes and found that the ‘ip routing’ command is not supported. I came across a document that stated “On switches running the LAN base feature, static routing on VLANs is supported only with Cisco IOS Release 12.2(58)SE and later.” So I have upgraded to 12.2(58)SE2, but ‘ip routing’ is still not a valid command.
The release notes state:“On the Cisco Catalyst 3560-X and 3750-X Series, it adds support for 16 static IPv4 routes in the LAN Base image.”
I have read other posts that talk about running the ‘sdm prefer routing’ command which I have done, but I am still unable to add any routes or run the ‘ip routing’ command.
I have an 1811 with several subnets connected to it.I recently installed a 3750x plant and want to bring my interior routing back to it.
All the routing is handled by the 1811 via secondary interfaces on vlan1?
I have 192 ports, and subnets show up on almost all of them. None of the ports are assigned to any specific vlans. Most ports have several subnets on them.
What is the best approach to getting the 3750x to handle the routing?
my company pay a switch 3750 X. WS-C3750X-24T-E. It uses IP services basically but I failed to configure InterVLAN routing. why interVLAN routing doesn't work on my switch?
