Cisco Switching/Routing :: 3560 - Cannot Do Simple Ping Anymore
Jul 5, 2012
A few days ago this was working properly, but I must have changed some things that adjusted some settings because I am unable to ping between 2 devices that are on the same switch, in the same network, in the same VLAN. I am able to ping to the VLAN interface on the switch.
This is my configuration (Catalyst 3560 Layer 3 switch):
ALGSWI01#show vlan
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Gi0/3, Gi0/4, Gi0/7, Gi0/9

I have the Cisco 3560 switch. I can ping both from switch to server or from server to switch. However, I cannot ping with large size, for example,
ping 192.168.1.1 size 10000 (failed all).
I can ping 192.168.1.1 size 5000
(the size allow between <36-18024>)
It's normal or a problem with the cable or something else? Because I have the error about working with MSSQL server 2008 R2, the error is:
[DBNETLIB][Connection Write (send()).]General network error. Check your network documentation
OS: Microsoft Server 2008 R2 Standard

We 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

I need to replace an ADSL modem and have a spare 857W. Can I use this to act as a simple bridge between the ADSL PPPoA connection and the FW WAN port?
[ CISCO 857W ]
ISP - PPPoA - BRIDGE - FW WAN
I have a block of Public IP's so the PPPoA Dialer 0 connection would get x.x.x.185/29 I would like to bridge this directly to the FW WAN port and set that to x.x.x.185/29 with a gateway of x.x.x.186/32.Currently I am using it in router mode with no NAT or FW and am losing a Public IP as I need to set the FW WAN as x.x.x.186 with a GW of x.x.x.185 I am setting BVI 1 as x.x.x.185/29 and Dialer0 as IP Unnumbered BVI 1.

For a simple ether channel to work between 2 switches I have configured ports 1 and 2 on both cisco 2960 switches with the channel-group option like this:
interface FastEthernet0/1
channel-group 1 mode on
!
interface FastEthernet0/2
channel-group 1 mode on
I thought the port-channel 1 would get automatically created but it didn't, should it? And under the port-channel interface should I set this as a trunk or do I do this on the 2 fa interfaces on each switch?

I have a very flat network. All of the gateways/SVI's exist on the same 6500. There are some vBrick IPTV servers that have a unicast address and 2-3 multicast addresses configured. After rebooting the 6500, the ip pim sparse-mode we had on all of our SVI's no longer work. I checked the old config and everything is the same as before I rebooted it. I troubleshot this for a while and found that the only way I can make this work now is if I enable ip sparse-dense on the SVI's. I believe this means that dense is the multicast method being used and I don't want to use dense mode because of all the flooding. How might I be able to make ip pim sparse-mode work again? I never had a static RP configured but I think I will need to. How do I decide on what ip address on the 6500 I should use as the RP? Should the ip address of the RP be a loopback address on the 6500 or should it be the SVI gateway ip of the vlan that the vBrick IPTV servers are on?

A customer contacted us that he can't connect his devices via web since he changed the IP address. Ok, big laugh "type the correct IP" but no. Even if you use the correct IP, no user can't connect anymore to the device. Also via CLI!The only thing that worked was the password recovery procedure. After that everything worked fine.The customer and me tried it again with another 2960, maybe there went something wrong when he did it last time and it was an accident. Nice thought but no: another device same error, no login possible.

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

I set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

i have a simple router on a stick config which is providing dhcp to a customer SSID. however i don't want employees to stay on it and eat the band width since its open. the lease is set to an hour, is there anyway that i could set it so that once your lease expired it can't be renewed for 4 about 8 hours? I am using a cisco 2600 router in this setup.

Cisco 3560 does not support "set ip next-hop verify-availabilty". I need this command in my config. "set ip next-hop" do not do the same job.

The last few days I've been exploring options in getting rid of some old routers accross a wan connections. I have a cat 3560 to play with and I thought I would try and use the no switchport command test out routing with switch. I've got some type of route issue and I tried a few things which I thought would fix the issue but had no effect. I'll post the config and a few commands so you can see what the basic setup is.
Here we can see in the arp that it knows about both 10.7.1.2 (PC unable to ping 10.3.3.254) as well as 10.3.3.254 (ASA).I tried adding in a ip route of 10.7.0.0 255.255.0.0 10.3.3.110 as well as 10.3.3.254. Neither produced the results I wanted allowing 10.7.1.2 (PC) to ping the ASA (10.3.3.254). [code]

I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?

I have tried to make policy based routing on Cisco 3560. I use ipservices ios (SW version 12.2.(50)SE3 and SW-IMAGE C3560-IPSERVICESK9-M) For below configuration there is no problem and pbr is working.
“Access-list 100 permit ip host 1.1.1.1 host 2.2.2.2
Access-list 101 permit ip host 1.1.1.1 host 3.3.3.3
Route-map pbr1 permit 10
Match ip address 100
Set ip next-hop verify-availability 1.1.1.2 1 track 11
interface fasthethernet 0/1
ip policy route-map pbr1”
But when i add another sequence to the "pbr1" with another sequence number like that.
“Route-map pbr1 permit 11
Match ip address 101
Set ip next-hop verify-availability 1.1.1.3 1 track 12”
pbr is not working. Switch gives message "PLATFORM_PBR-3-UNSUPPORTTED_RMP:Route-map pbr1 not supported for Policy Based Routing”"ip policy route-map pbr1" command not shown in the running config. And "show ip policy" output is blank.Configuration guide says you have insert many sequence to the route-map with the same name. And also this command is not in the unsupported command list.

We recently purchased Cisco 3560X Layer3 Switch. We need to perform simple Inter VLAN routing. We have configured VLAN1 (name-server_vlan) and VLAN2 (name- user_vlan). We have also assigned the Ports and IP address to both the VLANs. After assiging this if we plug Laptop A into VLAN1 then it doesnt communicates with Laptop B (btw, Laptop A is able to Ping VLAN2 Gateway ) in VLAN2 but on the other hand Laptop B is able to communicate with Laptop A and ping everything i.e. Gateway of VLAN1.

We have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?

I have a 2504 WLC connected to a Catalyst 3560 which has multiple vlans and is connected to a 2800 series router. I know the catalyst is L3 but I am needing nat functions to get outside to the internet. From my 2800 series router I am able to ping out to the internet, also I am able to ping the vlan interfaces on the catalyst switch. Problem is from the catalyst switch I can ping the inside and outside address of the 2800 but I cannot get any further then that. I cannot ping the 2800 router gateway. Not sure what I am doing wrong as far as routing.
I've attached my 2800 and 3560 configs.

I have the following setup.
host PC (192.168.9.3) -----> gateway (192.168.9.2) ----- Pix E1 (192.168.9.1)/Pix E0 (81.x.x.250) ------ Internet
The 192.168.9.2 gateway is a 3560 switch connected to the PIX. I can ping out to the Internet via IP from the PIX, but not via the host PC (192.168.9.3) on the LAN. PIX and gateway configs below. Am I missing something that's preventing me pinging out to the Internet from the internal LAN?
PIX config
test-cal-pix01# sh run
: Saved
:
PIX Version 8.0(3)

hostname test-cal-pix01
enable password btf1YD.Vq7mE6vEA encrypted

I have a 3560, which is being used as our core router that I have recently installed. It still has the standard IOS which came with (C3560E-UNIVERSALK9-M) it but I need to implement policy based routing so need to upgrade it and have downloaded c3560-ipservicesk9-mz.122-58.SE2.bin and indeally would like to install it in the morning before people start work.
I have 2 questions, 1, Is the ipservices capable of PBR as I have been reading conflicting reports, in fact my friend who works for Cisco has advised that it is not possible on the 3560.
2, When I do upgrade will there be any current configurations that are not compatible with the new one, I wouldnt image that there would be any but just wanted to make sure as it would be the biggest headache ever if it went wrong.

I have a 3560 POE that will no longer boot and I am not able to load a fresh copy of software onto it. It appears that it has lost all data. When I attempt to TFTP a new IOS, I receive that following error:
Transfer cancelled by remote system
I have tried using dir flash: to see what is contained in the flash directory but I receive the below message:
unable to stat flash/: no such device
I am stuck in rommon mode so when I do switch: dir command, I don't even see flash as being a filesystem. The below list are the only systems registered.
bsdcs[0]: (read-only)
bstage[1]: (read-only)
fstage[2]: (read-write)
xmodem[3]: (read-only)
null[4]: (read-write)
tftp[5]: (read-only)
Is this switch finished or is there something else I could try?

I have issue with 3560 switch QoS configuration . I checked in cisco site about mentioned model QoS configuration.once we mark the frame and map the CoS to DSCP and once it enters into switch and it processes according to LAN QoS configured on interface
we have configured both the commands shape and share.
once it leaves the switch and enters into Edge router and if we do not have configured QoS in router which is normally MQC , how does it process each packet ?Do we need to have end to end QoS configured in LAN ?

I found that when I enabled layer 2 auto QoS in 3560 switch, I need to wait so much time to open a file in network drive. Howerver, when I disable the Qos. It can improve a lot. I have used a sniffer to capture the packet to see. Those default packet is in DSCP 0. Therefore, I think majority packet will drop to queue 4. How can I increase the buffer and threshold in order to improve queue 4 performance.
