Cisco WAN :: 3560E - VTP And HSRP Configuration On Two Core Switches

Feb 27, 2013

I have configure multiple vlans on both the core swithces below is the example, my question is how will be my VTP server configuration on the 3560E since both the core switches will have identical vlans HSRP 2 configured on them. Do I have to configure both the cores with same DOMAIN NAME ?

The core has VTP 2 so I cannot use primary and secondary option.
 
CoreSwitch1
interface Vlan713
ip address 194.43.86.251 255.255.255.0
standby version 2
standby 86 ip 194.43.86.1(code)

Cisco Switching/Routing :: 3560E - HSRP Gateway Failover And Routing Table

Nov 12, 2012

We have two Cisco 3560E layer 3 switches at the core of our network. The switches are configured as an HSRP pair and the clients on our network point to the HSRP address as their default gateway. So if CORE-A dies, then CORE-B will pick up the address and the default route for the clients will continue to be available.We also need to specify a few static routes on the core switch to allow us to get to specific networks. Is there a way to do this so that the routes failover in the same way that the default gateway does?

Cisco Switching/Routing :: 3750 Stackable Switches Etherchannel To Core Switches

Nov 18, 2011

If I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?

Cisco Switching/Routing :: 3750 Stackable Switches And 6509 Core Switches

Nov 14, 2011

If I have two stackable switches were only one stackable switch has two uplinks one uplink goes to one core 6509 switch and the other uplink goes to the other 6509 core switch can a Layer 3 etherchannel be used if each uplink go to a different core switch, by the way hsrp is running between both switches and also can you give an example how data will be routed from the stackable switch through the ethernetchannel to one of the core switch accross the WAN to another core switch?

Cisco WAN :: 877 / 2960 - HSRP Configuration On VLan1

Nov 13, 2012

I have the following topology:

2x 877 routers, one interface from each router (port Fa0 which belongs to the router internal switch) is connected to the 2960 switch, the switch himself configured with default settings, flat with one v LAN.

I have configured HSRP in the following manner: router A is 10.0.0.2, router B is 10.0.0.3, virtual IP is 10.0.0.1, take note that the HSRP configuration along with the IP address are configured on vlan1 interface.
 
Now when i connect a PC to the switch with static IP (10.0.0.4) and trying to ping 10.0.0.1 I'm not getting replies. i see on the PC, using wire shark, the icmp request goes out but on the primary router (and also on the backup) i can't see the icmp request (using debug ip icmp).
 
this behavior happens only when the HSRP is configured on interface vlan1, when configuring the same configuration on Fa4 (which is WAN interface) everything works fine.

Cisco Switching/Routing :: 2920 - Sub Interface Configuration / HSRP Address

Aug 16, 2012

Having 2 router with 2 sub interface configured with HSRP. The server sending the data have the route default gw xxx.xxx.xx.252 HSRP address. But on of the routers did got HW problem so we did shut it down, R2 with IP xxxx.xxxx.xxxx.251, problem so the traffic didn't go there correct when was using the HSRP address some packaged went there but not all of them no blocks in the logs. But then we did change the server direct to  to the working router R1 xxxx.xxxx.253 everything did start working fine again. was working fine. Logs i got in the router was max tcp half-open connections.
 
I am wondering if something wrong in the configuration below and why the traffic didn't got there correct when using the HSRP address. Its working fine when using R1 IP address. The devices are 2 Cisco 2620 routers.

Cisco Switching/Routing :: Using 6509 Series As Core Switches

Jun 2, 2012

we are using cisco 6509 series switches as core switches. and Cisco 4510,4507 series switches as edge switches. all the vlans are created at core switches and propogating to edge switches through VTP. we are using OSPF as routing protocol at core switch for internal routing. till now we are using 4510,4507 switches as layer 2 switches. Since, 4510 & 4507 switches are hign end swithces i want use them as layer 3 switches instead of layer 2.if i change these switches from layer 2 to layer 3 does it make any impact on our network or better to keep them as layer 2 switches.if i change these switches to layer 3 is there any advantage i will have.

Cisco WAN :: 6500 - Connecting Servers To Core / Distribution Switches

Feb 10, 2013

We are using CISCO Catalyst 6500 switches as collapsed core/distribution switches (2 layer architecture). I want to connect approximatly 10 application servers to the network. Can I connect the servers directly to the catalyst 6500 switches using WS-X6148E-GE-TX line cards? The other option is to use access switchs and then connect the servers to the catalyst 6500 through access switch(Catalyst 3750).

Cisco WAN :: Multicast On 4510 Core Switch And 3750x IDF Switches

Jul 15, 2012

At our site we have a 4510 core switch and 3750x switches in our IDFs. The 3750 switches are connected to the core via DOT1Q trunks in a server client setup. We are putting in an Informacast/Berbee server witch will send pages and text to the cisco phones. We also have 1 3750 switch connecting to the core via a layer 3 port channel. If we put the Informacast server on the phones vlan would I just need to enable ip pim sparse-dense mode on that vlan only and enable multicast routing, ip multicast routing?

Cisco :: Core Layer Switches After A Spanning-tree Topology Change Occurs

Mar 24, 2013

I've been taught/under the impression that vlans and stp stay in the access layer to prevent bridging loops and broadcast storms from taking down the whole network. Well I was reading about backbonefast and how it "Enables fast convergence in the networkbackbone or core layer switches after a spanning-tree topology change occurs." Now I thought that from the distribution layer up we use a routing protocol.

Cisco Firewall :: FSWM Active / Standby Installed In 6509-E Core Switches

May 9, 2011

I have FSWM active/standby installed in 6509-E core switches running following FWSM Firewall Version 3.1(3) Device Manager Version 5.0(2)F..I want to upgrade to latest FWSM version as well as ASDM, I downloaded asdm-622f.bin and c6svc-fwm-k9.4-1-5.bin from cisco portal. When i checked the show version of FWSM, it says..The Running Activation Key is not valid, using default settings: Running Activation Key: 0x00000000 0x00000000 0x00000000 0x00000000
 
I have gone through threads on CSC about how to upgrade FWSM in failover mode, now my concern is, Do i have to take care about activation key or keep as it is ? I have maintenance contract with cisco for all devices.

Cisco Switching/Routing :: Connecting 5548 Pair To 2 6509 Core Switches / No Vss

Jun 8, 2012

connecting a 5548 pair to our core 6509s.  Just want to be sure we don't introduce any issues into the network.The 6509's are connected and perform all the routing.  Essentially, we're moving away from a 3750 stack in the data center and the 5548s are the replacement.  We'd want to limit the vlans to the specific server network vlans. Our current setup is a port channel between the 3750 and each of the 2 6509s for redundancy. I'd like to use the same functionality when we connect the 5548's but I'm looking for what the config should look like to ensure no spanning tree loops are introduced and that it is configured optimally.

Cisco Switching/Routing :: 3750 / 4507 - Upgrading Core Switches With Nexus 7010

Feb 8, 2012

The company I work have finally decided to enter the 21st century and invest in a new telephone system (Interactive Intelligence) to replace the legacy system which has served us well for the past 10 years. The project has only just started and involves upgrading sections of CAT3 cabling to CAT6, replacing Cisco 3550 switches in one area of the building with Cisco 4507 switches and upgrading our Core switches with Cisco Nexus 7010's. The area that concerns me most is enabling the network for qos as I have very little experience with it. At the moment Im trying to read as much documentation as I can on QOS to bring myself up to speed.
 
The access layer switches will consist of a mixture of Cisco 3750 & 4507 switches connected to Cisco Nexus 7010 switches which will form a collapsed aggregation & core layer.
 
Basically, how I should approach this daunting task of making sure the network will support VOIP.

Cisco Switching/Routing :: Output Queue Drops On 3750 Core Stack And 3560 Edge Switches

Jan 10, 2013

I've been fighting what seems to be an increased number of outqueue drops on our core stack and edge switches for the last 3 or 4 weeks.(The core consists of a stack of 5 3750s in 32-gig stack mode. The wkgrp switches are 3560s. all are at 12.2.52) The  wkgrp switches are directly connected to users. We use Nortel IP phones with the phone inline with the user PC. auto-neg to 100/full. [code] However I have tried turning off QOS on a couple of workgroup switches (no mls qos, but left individual port configurations the same) but am still seeing drops.Since I have disabled qos on the switches in question (no mls qos)  (not the core tho) I am presuming these commands have no affect on the switch operation and therefore cannot be related to the problem. With QOS turned off one would presume that it is general congestion - especially at the user edge where busy PC issues might contribute. So I wanted to see if I could see any instances of packets in the output queues building up.
 
 I wrote some scripts and macros that essentially did a snapshot of 'show int' every 20 seconds or so, and looked for instances of 'Queue: x/' where x was greater than zero.What I found after several days of watching the core stack, and a few of the workgroup switches that are most often displaying the behavior, was that I NEVER saw ANY packets in output queues. I often saw packets in Input queues for VLAN1, once in a great while I would see packets on input queues for fa or Gi interfaces, but NEVER on output queues. [ code] Additionally, when I look (via snmp) at interface utilization on interfaces showing queue drops (both core and wkgroup), they are occurring at ridiculously low utilization levels (as low as 4 to 8%). I've tried to look for microbursts between the core and a wkgroup switch where the core interface was experiencing drops, but haven't seen any (using observer suite). [code] While the queue-drop counts aren't critically high at this point, they are happening more frequently than in the past and I would like to understand what is going on... In most cases, no error counters are incrementing for these interfaces. Is there some mechanism besides congestion that could cause output queue drops?
