Cisco Routing :: Catalyst 6500 / 4500 - Preventative Maintenance On Catalyst Chassis Switches?
Jun 4, 2013Are there any best practices for preventative maintenance on Catalyst Chassis switches. Looking to build a PMI schedule for a customer. Or is there evidence not to perform it at all. Things like re-seating line cards, cleaning fan exhausts, etc.

Feb 12, 2013At the moment our whole company is equipped with Catalyst switches ranging from 2950, 2960 to some 3560G and 3750X (Cores). Now I'm thinking of replacing some of the old 2950s (which are only fast ethernet) with some Brocade 6430 or 6450s, since they're so much less in pricing.My concerns though are: will spanning tree work problem free, access lists still work and any other problems I could encounter with interoperability.According to Brocade most of these things should work fine, but I'm searching for some facts from people who are running a heterogenic Network with these two brands (even the same product lines).

Sep 27, 2010a customer purchased a ESW-520-24p to be used in a VoIP project. Today we had difficulties connecting it to a Catalyst 3650G switch; We've tried setting the port to trunk, general, customer and access and changed all sorts of VLAN settings on the 3560G switch to no avail: the switches just wont interconnect. While sniffing we saw that ARP requests are even not answered, so something is wrong on a low level, probably with VLAN-ing.if these switches should be able to be interconnected and if yes, what needs to be done to do so?
Secondly; voice will be on seperate VLAN and the client will use SPA942 phones, which have an internal switch that allows to connect a PC to it. I've used this phoned successfully with Catalyst Express switches and I didn't have to do anything for VLAN-ing, this worked "out of the box". Can these phones work with the Small Business switches as well?

Feb 10, 2013We 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.
Cisco Switching/Routing :: Trunking Between Catalyst 2950 Switches?
May 14, 2012have 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.

Cisco Switching/Routing :: Auto-QoS On Catalyst 3750 LAN Switches?
Aug 12, 2012why the AutoQoS macro does not implement "priority-queue out" when configured on the 3750 platform running certain versions of software. The only other platform I have experience with AutoQos is on the 4500 and it enables priority queuing as expected. So what's up with autoqos on the 3750 on version 12.2(35)SE5?
When it comes to configuring QoS on campus user/phone access ports there are some important settings that can and should be considered but one can argue that enabling the priority queue is the single most impactful or important command. So I was very surprised and concerned when I didn't see priority-queue out. Cisco describes AutoQoS as a simple, quick way of deploying QoS on the LAN and it precludes you from having to learn all of the differences between hardware platforms. But is it true that this tool produces an incomplete config solution? Let me know if I am missing something.
Here is an example of what AutoQoS produces when applied to a 4507 with WS-X4648-RJ45V+E:(other interface commands are left out for simplicity)
interface GigabitEthernet5/25description XYZ
switchport mode accessauto qos voip cisco-phoneqos trust device cisco-phoneservice-policy input AutoQos-VoIP-Input-Cos-Policyservice-policy output AutoQos-VoIP-Output-Policy

Here is an example of what AutoQoS produces when applied to a 3750 running version 12.2.(35)SE5: (no priority-queue out)

Cisco WAN :: WS-C3560G-48TS-E / Cold Startup Time For Catalyst Switches?
Apr 23, 2013My customer uses WS-C3560G-48TS-E switches in air traffic control systems. A requirement for one project is that the entire system be up and running in under five minutes. The WS-C3560G-48TS-E and its replacement - WS-C3560X-48T-E with C3KX-NM-1G - take about four minutes to start up. With other devices added in they exceed their required startup time.They also use WS-C3560V2-48TS-E switches which take about two minutes to start up but they want they GE.
1) Is there way to improve the start up time in the WS-C3560G-48TS-E and WS-C3560X-48T-E switches?
2) Is there another Catalyst switch with similar specifications to WS-C3560G-48TS-E and WS-C3560X-48T-E that has a quicker start up time.

Dec 15, 2009I have couple of Linksys SRW 224G4 and SRW 2024 connected together with Cisco C3650 switches. For my part of network VLAN100 is used as administrative vlan and VLAN1 as defult (on trunks or unused ports).Altrough most of switches work fine, on all older models of SRW224G4 (hw 1.0, various firmware versions) there is no connectivity to management utilities (also ping won't work) via trunk (where of course VLAN100 is present). At the same time there is no problem with access from "local" ports (assigned to VLAN100) and there are no problems with traffic on VLAN 100 along the network.
For example:Two computers (A and B), two switches (sw1 - old SRW224G4 and sw2 - Cisco switch), are connected as follow:
A--VLAN100--sw1--TRUNK--sw2--VLAN100--B
Swicthes have VLAN100 as management VLAN, computers are connected to access ports (untagged).A has access to management on sw1 and sw2 and connectivity with B?B has access to management on sw2 and connectivity with B but has no access to management on sw1...If sw1 and sw2 are same, old SRW224G4 - everything works fine.Newer versions of SRW224G4, SRW2024 and SLM2024 works OK.Why it doesn't work?
Cisco Switching/Routing :: Catalyst 3560 / 3750 - Can Ping PC From Switches But Not From PC
Feb 19, 2013We have a couple of Cisco switches and connected a (Windows 7) laptop to one of them and it gets its IP address from a DHCP server.I can now ping the IP from all of the switches, no problem, also not when I log on to the core switch in the same VLAN as both notebooks. But from my (Windows 7) laptop, which is in the same VLAN as the target laptop, I cannot ping it.
I checked, default gateway is good on both sides, as are DNS servers.
Target notebook ---- Catalyst 3560 V2 switch === Core Catalyst 3750 switch (stack) === Catalyst 3560G switch --- My notebook
Cisco Switches :: 200 Learn Voice VLAN And CoS / DSCP From Catalyst 2960?
Oct 31, 2012How can I configure Cisco 200 (SG200-08P) to learn Voice VLAN and CoS/DSCP from upstreamCatalyst 2960?
The Cat 2960 is today used together with LLDP-MED to announce config to Aastra IP Telephones. In some cases I need to use a small switch inbetween and plan to use the Cisco SG200-08P for this. However, I would like to avoid manual config of the Cisco 200 switch.
Cisco Switches :: Catalyst 4510 - Integrating SG200 Into Existing Network
Dec 17, 2012We have an existing network with a Catalyst 4510 core switch and departmental 3560 switches connected via fiber. Due to company restructure we can no longer afford to buy new 3560's when anything goes wrong so this week I purchased an SG200-26 which I'm trying to get onto the network.
This is a legacy network which I didn't setup so my Cisco skills are somewhat limited (another reason for the SG200's hopefully), anyway have been looking at the configs on the existing switches and trying to match settings in the SG200 setup however not getting anywhere! I have the config from the dead switch so I can show what needs to be achieved, any experience in downgrading environment in a similar way?
Cisco Catalyst 2950 - GigE Switches With 64bit IF-MIB SNMP Counters?
Oct 18, 2011which models of HP ProCurve or Dell PowerConnect support 64-bit IF-MIB counters, or for that matter any other manufacturer (Zyxel?) (snmpv2 or v3, OID .1.3.6.1.2.1.31.1.1.1.6)I believe pretty much any Cisco Catalyst above a 2950 do, however don't believe any of the SG series do. I realize I could pick up a 2960G for $1500-2k and be good to go, but I forsee a larger switch purchase in the future, but still could use a switch in the meantime that was able to allow accurate monitoring of closet uplink bandwidth?

Sep 5, 2012I've been conducting research on configuring 3 distribution switches in my network which are Cisco Catalyst 4507's to communicate with our core over layer 3. Our core switch which is already configured at Layer 3 for intervlan routing is a Cisco Catalyst 6509.
I've got the configuration portion complete and all devices are able to communicate my only question is about QoS. Do I have to configure QoS at the layer 3 interfaces for voice, if so how is that completed. We have several vlans and separate the vlans for each building by voice and data. We only configure ports on the access switches with voice vlans for QoS and we use the auto qos option on these interfaces.
Cisco Switches :: Single Mode Fiber Link Between SGE2000P And Catalyst 2960?
Jun 4, 2013I'm working with a customer who has an SGE2000P and a Catalyst 2960 to setup and configure a single mode fiber link. The SGE2000P has an MFELX1 fiber GBIC and the 2960 has a GLC-LH-SMD GBIC. When I have the customer plug in his fiber, there is a power light that comes on on the MFELX1 GBIC. Neither GBICs/switches show that a link or activity is occurring, but the presence of that light makes me think that they are connecting somehow. Are these two switches/GBICs compatible?

May 10, 2012Does a portable RPS device either from Cisco or another manufacturer exists, that would allow you to move primary power for a switch without causing an outage? I realize that for the Catalyst 3560 for example, you can get an RPS 2300 or 675, but my understanding is that these are made for a more permanent installation, not to mention rather costly.
It looks like the RPS 675 is rather inexpensive after all, especially in the secondary market, but still rather large for toting around.

Aug 20, 2012I have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
