Cisco Switching/Routing :: 3560x - Lan Base 4900M Can Take Load Of 18 Access Switches

Feb 6, 2012

We are using 18 numbers of 3560X -Lan base series switches in our network(Access layer). We have 400 users and created vlans in access  switches. we are planning to purchase Two numbers of 4900 M as Core layer switch and for redundancy. The uplink would be on 10 gig copper cable (CAT 7) between the access layer switches and core switches. I like to know whether 4900M can take the load of 18 access switches.

Cisco Switching/Routing :: 3560 V2 Stacking With 3560X?

Mar 14, 2012

Im going to be ordering a new 3560X L3 switch (ws-3560x-48pf-s). We currently have a 3560 V2 switch and I've read it supports stacking, but looking at the back I just see a console port. Is there an extra card I have to get for this 3560V2 to make it stakable with the 3560X?

Cisco Switching/Routing :: Feature Set LAN Base / Lite (2960) And LAN / IP Base (3650X)?

Mar 28, 2012

1)For 3650X I found some contradiction in the Q&A about feature set LAN Base vs IP Base:

LAN Base: Can I do static IP routing ?
LAN Base: SVI => is this for intervlan routing ?
2)For 2960, there are 2 flavors (LAN lite and LAN BASE) Q: Can I do static routing on one of these flavors ?

Cisco WAN :: 3560X With IP Base In The Ring

Dec 27, 2010

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.

Cisco WAN :: Auto-summarization Disabled In EIGRP On IP-Base 3560

Oct 4, 2012

I'm running IP Base on my Catalyst 3560. I'm aware of the fact that this license only allows for EIGRP stub routing - this is desired. However, I don't seem to be able to run the "no auto" command to disable auto-summarization. The command works, but doesn't make it into the running config.
3560-1(config-router)#no eigrp stub connected
EIGRP is restricted to stub configurations only on this platform.
3560-1(config-router)#no auto

Not a huge deal since a "show ip prot" indicates that auto-summarization is already disabled, so I'm guessing this is why "no auto" will not take. Why auto-summarization is disabled by default in my scenario?

Cisco Switching/Routing :: 3560X Not Connecting At 10 / Full

May 14, 2013

I 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:

Cisco Switching/Routing :: 3560X Multicast Traffic Should Not Appear

Feb 18, 2013

I have a 3560X switch with interfaces 36-48 on the same LAN. All interfaces are switchports. Hosts on 38, 39 and 40 are multicast senders: all sending to the same single multicast address. Hosts on 36 and 37 are receivers, having joined that multicast group. I created an SVI for the LAN and put it in ip pim passive. (That is the only PIM mode allowed for an SVI with my IOS.) Show ip igmp snooping groups shows that 36 and 37 are the only interfaces in this group. I attach a laptop to interface 42 and Wireshark, and the laptop is receiving the multicast traffic. The laptop does not join the group. I expect it would not see the traffic.

Cisco Switching/Routing :: 3560x Blocked ARP For 300sec

Jan 25, 2013

last week we have changed the connection of small town from licensed radio to direct fiber with clasic 1gig sfp.After that we have connected the new fiber , we can see 5 min outages of customer internet connection. If we are conncted on the same subnet anywhere on network, we can ping the customer all the time. But if we try to ping the customers public IP it is each 5 min for 5 min unreachable. I have tryed to sho logg in all switches but there are no mesasages. I just see, when comunication have lost, the MAC and IP of customer will disapear from routers ARP tabbel. What is going on?When i enter sho mac address-table i can see customers MAC address in all switches. There are exactly 5 min outages. 5min it runs ok, 5 min outage and it repeats agan.
I looks like the swith blocks the ARP packets from customers to their default gateway.The routers are connected to catalyst 3560x lan base ios, This switch is connected to another 3560x lan base ios and it is connected with fiber to ME3400 where are customers connected.

Cisco Switching/Routing :: 3560X Crash And Reboot On IOS 15.0(2)SE

Jan 24, 2013

I have 3560X-24T-S switches with IP Services loaded at remote sites that I have been having troubles with.  Originally, they had IOS 12.2(58)SE1 on them.  I have up to four diverse paths via point-to-point microwave at the remote sites.  The Microwave equipment is by Microwave Networks and is a Prodeus M series which Ethernet support.  The original issue manifested itself as hardware loopback errors on some of the ports that were connected to the microwave links.  
My experience in the past has been that when a hardware loopback error occurred it is usually a bad switch port.  In this case however, if I disconnected all of the microwave Ethernet links and rebooted the switch and then connected the Ethernet connections to the microwave links again, everything works fine.  No hardware loopback errors.  That is, until the next switch reboot.  Then the hardware loopback error would return.  Interestingly, it would come back on different ports connected to the microwave links every time.  So if a reboot was done without disconnecting the microwave Ethernet links the hardware loopback error would change from one microwave link to another after each reboot.
I then went through and read the lengthy release notes for IOS version 15.0(2)SE and found several fixes that I thought could fix my issue.  So I downloaded it and updated a couple of the offending switches (not all of them were having this problem).  After going through the second update required to resolve the 'open file error' that happens going between 12.2(58)SE1 and 15.0(2)SE the problem seemed to be resolved on the offending switches.  So, I went ahead and updated the IOS on all of the switches with point-to-point microwave connections.
I now have one switch that was updated that is crashing and rebooting continuously when the Ethernet links for the point-to-point microwave are connected.  Again, if I disconnect all the microwave links and reboot, it comes up fine ands stays fine when the microwave links are connected back up.  It will work fine until the next reboot and then the crash and reboot loop starts over again.  Below is a portion of the putty log when the crash occurs:

Cisco Switching/Routing :: 3560x / HSRP On LAN And WAN Interface?

May 9, 2012

I currently use L3 switches as edge routers to my WAN. I want to use a pair of 3560x switches with IPbase to provide a failover path to my WAN using HSRP at one location but had some problems testing the configuration. My plan is use a virtual address on the LAN interface (VLANx which port gi0/1 accesses) and the WAN interface (VLANy which port gi0/24 accesses). I want switch 1 to be primary since it will have an IPS attached to it, and switch 2 will be backup and used only when switch 1 or the IPS requires maintenance. On both the LAN and WAN sides there is no advanced routing going on, the various hosts just depend on the availability of their respective default gateways, so HSRP should be sufficient to provide a failover in either direction.
In my testing I got 1 or the other link to fail over but not the entire switch. What should my config look like to achieve failover of the entire switch in the event 1 or the other interface goes down, and fail back when the primary links are again available?

Cisco Switching/Routing :: Default Username On 3560x?

I am stuck at a very early stage in the configuration of 3560x switch. It seemed very unusual and that is the reason, I configured basic config for line con 0 with login local. And then I had just put "enable secret xxxxxx."
Now I simply logged out and when i tried logging in, it is asking for a username. Now the thing is that I had not programmed any username. I tried using just "." followed by my secret password, but it did not work.

Cisco Switching/Routing :: 3750X Static Routing When Running LAN Base?

Dec 27, 2012

I 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.

Cisco Switching/Routing :: 3560X Not Switching To PoE+ 30W

Aug 26, 2012

I have a Cisco 3560X series 48 port PoE switch which im using to try to power a Axis Q6032E PoE+ PTZ camera that requires 25W of power. Although when I plug the camera into the switch it power as PoE Class 4 but will only assign the port 15.4W of power. I have tried going into the switch and manaually assigning the port to 30W of power but no luck. I have talked with the Axis vendor and they stated that Cisco does not turn on 802.3at protocol by default? This does not seem correct. I am running a single 1100W power supply as well. See output below. Gi0/43 is port in question.

Cisco Switching/Routing :: 3560X Not Booting And No Lights Except On PS Module

Mar 3, 2013

I have a brand new 3650x switch that I was configuring via console and left it on overnight; this was friday night  ( I forgot to keep the air conditioner on).  When I returned Sunday afternoon and checked the switch I realized that the SYS and STAT lights on the front were not on, however the Leds on the PS module were still on.  I powered it down and turn it on again but still there are no lights on the front.  The PS OK and AC OK leds on the PS module are on but I noticed the leds on the two fan modules are not green or even amber; they are off.When I first turned on the switch I remembered distinctly that there were loud noice and if all fans were in overdrive mode for a few seconds then the went  to normal.  I'm not gettgin this loud noise phenomenom.
