I have a really weird issue with my cisco catalyst 3560G.
-device: cisco catalyst 3560g
-ios: 12.2-53(SE) IP SERVICES
scenario: configured IPv6 iBGP link between this switch and a router. the router is announcing 1 (test) route. the switch sees the route properly, but doesn't add it to routing table (the route never gets to be "best path", although it should be).
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?
A check out a network segment and want to know why SwA has a static route to SwB if SwA already has a Default GW to Core?
(SwA, SwB - Catalyst3560, Core - Catalyst4948)Note, there are distribute list on SwA - it does not has any OSPF route (exclude O*IA).
Does this mean when SwA send out packet with DA 10.5.64.0/26, Core will use only L2 switching (instead of L3)? Is this more effectively for Core Switch?
Pleace check my reasoning:
1. When use a static route: SwA receive packet from Vlan 20 with DA 10.5.64.0/26 it will strip out Dest. MAC and replace it with MAC of SwB. Core will switch this packet to SwB based on mac add. table (l2 switching)
2. When SwA has only Default gateway and receive packet from Vlan20 with DA 10.5.64.0/26 it replace Dest. MAC with Core MAC. Core receive this packet, lookup route table for 10.5.64.0 entry and forward packet base on this.
I have been researching a way to remove this subnetted route from my L3.There is an extra subnetted route that should not be there when I execute the command: show ip route
Below if part of my Show Run and the Show IP Route commands. You will see the 10.0.0.0/24 subnet as subnetted. I dont know why the L3 uses the 10.0.0.0/24 when I enter 10.10.10.0/24? But thats a whole different questions.

We have a cisco 3750-48 port switch.We have a few SVI's configured and some static routes configured.I had created a new interface vlan and gave it an IP. I can ping the gateway.
Now I want to add a static route to go out that interface.when I add: ip route 10.x.x.x 255.255.255.0 10.52.10.1
it eccepts it (no errors) But, it does not show in the routing table nor in the config? How to add the static route to go out that vlan interface.
Any way to test in a lab what would happen if a tech mistakingly added "switchport voice vlan XX" to a trunk port? I am try to do some RCA on an issue and this has been identified as a possible cause by one of my techs.
The config is Switch1------Switch2--------Switch3 Each interswitch connection is configured as a dot1q trunk with all vlans allowed. The link between switch2 and 3 is where switchport voice vlan 10 was added. Switch1 is a 3750 and 2/3 are 3560's.
Having an issue with two Cat 2940, they have fiber 100Base-TX. Added a new Cat switch (the second on the VLAN), the existing Cat switch drops the fiber connection.
View 6 Replies View RelatedI have a Catalyst switch that is redistributing some static routes into OSPF. These are received on a Nexus 7K and appear in the database however the 7K does not add them to its routing table, one of the routes is ignored and not added. I haven't got a clue why this is happening.
The routes on the Catalyst are as follows with ID of 172.30.255.22:

Just I have upgraded some 2960S to IOS 15.0(2)SE from a IOS 15.0(1)SE3 and the catalyst don't switch any IPv6 traffic. Don't work any RA and also don't work any unicast IPv6 traffic from any interface. I can see some references to IPv6 changes in the FHS (First Hop Security) in the Release Notes, but no any reference to changes in the configuration.
The switches don't have any IPv6 specific configuration and the sdm is the default templata. Returning to 15.0(1)SE3 everything work ok.
On Catalyst 2960, and 3560E this IOS version seem to work fine with IPv6.
We have a IP-phone system connected to port 1 on a 3560 switch, the phone system tags traffic with dscp. The switch uplink is on port 24.
Is this configuration correct:
interface 1:
auto qos trust
interface 24:
priority-queue out
I have Catalyst 3750. and 2 ISPs
I wanted to use, let say on port5 of Catalyst 3750 only 2nd the ISP will route to this port.
The rest is pointed to the 1st ISP.
Im thinking of using VLAN..
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.
Does the Catalyst 3560 support GRE ?
I know that Catalyst 3750X support GRE ,but Catalyst 3750X cannot work in hardware it.
Does the Catalyst 3560 cannot work in hardware too?
I'm currently configuring per port policing on a 3560 and want to limit inbound traffic to 750mbit:

When I test the setup with iperf I always get different results when I change the nummber of parallel connections.Isn't there a way to limit the throughput regardless of the number of conns (INGRESS!) like with srr-queue bandwith limit?

I'm having an issue with 2 of my 3560s which are not booting. The last thing I did on both switches before it hangs was:
>write erase
>reload
restarted as normal

I've tried powering-off the switch and pressing the Mode button and power on. I got to swtch: mode switch:reset
It restarted past the POST but just hang halfway at the same bootp-up process as shown on the attached. The SYST LED is Green color when it hangs.
My first question is I have an access layer switch which is a single VLAN and I am trunking that VLAN to a distribution layer switch, I can ping the gateway on the distribution layer switch for THAT VLAN, But cannot ping the gateway address for the second VLAN I have on the distribution layer switch. I know it is simple, But I have forgotten and just need a push
Also I have a third VLAN set to route traffic not bound for those 2 VLANs out to a router is the statement "ip route 0.0.0.0 0.0.0.0 172.16.252.2" good enough and do I actually need to create a VLAN for that traffic? and if so, is an access switchport the best option?

The 3560 switch is serving as an access and distribution layer switch. End devices are connected to it and it also implements IP routing via SVI and L3 ports.Auto qos voice cisco-phone has been implemented on applicable access layer ports. SRND4 is being used.
2960:
mls qos map policed-dscp 0 10 18 24 46 to 8
mls qos map cos-dscp 0 8 16 24 32 46 48 56
mls qos srr-queue output cos-map queue 1 threshold 3 4 5
mls qos srr-queue output cos-map queue 2 threshold 1 2
mls qos srr-queue output cos-map queue 2 threshold 2 3
mls qos srr-queue output cos-map queue 2 threshold 3 6 7
[code].....
Question 1:Why is the auto qos generated policed-dscp map different on these two switches?The Cisco Smart Business Architecture LAN configuration files guide [URL] does not specifically use the 3560 in their examples, they use the 3750 but it's my assumption that the same techniques, configs apply with regard to my specific feature questions. When using a 3750 in the Access layer, the guide shows (page 15) the same auto qos generated policed-dscp map configuration that is on my 2960. The SBA LAN config guide shows that when using a 3750 as a Distribution layer switch (page 26), the policed-dscp map configuration is the same that I see on my 3560.In the configuration guide for the 3750 distro switch, there is no auto qos applied as there are no access ports, so the mls qos commands are manually input. Since my 3560 does have access ports, auto qos generated the mls qos commands, and the results are the same be it following the guide and manually entering (per distro switch guidelines) or using auto qos. This leads to question 2...
Question 2:Why is the mls qos map policed-dscp configuration different depending on use as an access vs. distribution switch?
Question 3: On the 3560, access ports that have "auto qos voice cisco-phone" applied are put into queue-set 2 (output). Queue-set 2 (output) uses default values (not configured). Is this correct and desirable? If so, why? The 2960 has all ports in queue-set 1, regardless of being an access device port or a trunk port connected to the 3560 (as per the SBA LAN config guide EgressQOS macro commands). The 3560 trunk ports are all also configured to use queue-set 1 (output), again as per the SBA LAN config guide EgressQOS marco commands.
It is possible to configure the IOS NetFlow 122-58.SE2 in a Catalyst 3560?
View 5 Replies View RelatedI have one specific trouble with Catalyst 3560CG switch and Stardom reserved industrial controller. Controller has 2 processors, one of them after(!) negotiation become main with IP 192.168.1.1, other one stays in reserve with IP 192.168.1.129. If main one shuts down, spare one becomes main with IP 192.168.1.1. This perfectly works with DLINK and MOXA level 2 switches, but fails with Catalyst 3560, because spare one cannot even connect to switch port. I don't know the exact reason of it, but i suspect, that it happens because of before negotiation both controllers have ip 192.168.1.1 (i know, that it is wrong and weird, but so it goes). First of them correctly connects to switch port, which goes up and passes pings. Second processor tries to connect to switch port, which goes several times up and very soon down, then processor lefts his tries to connect to anybody and become idle. The switch seems to some way check IPs of 1-st and 2-nd port packets, and shuts down 2-nd port. I have connected via hyperterminal and tried to disable some level 3 functions and checks of the switch, but this wasn't useful. how exactly(or at least approximately) should i configure a switch to make this bundle work?
View 1 Replies View RelatedI've just installed 2 of these in my workplace on a PLC network.I'm now looking to set one of the ports up as my diagnostic port and would like to be able to mirror any of the other ports to this port.I believe it is called SPAN on Cisco switches.The only reference I can find to it is configuring via Telnet which I haven't got a clue about.On my old Wiedmuller switches it was just a few clicks away.
View 3 Replies View RelatedI have 5 SVIs configured for VLAN Interfaces 121-125 for my vSphere environment.
All VMs can ping IPs on all the VLANs (VMs on VLAN 124 can ping VMs on VLAN121)
All VMs, except those on VLAN 124, can access the Internet or even ping my router IP.
If I change one of the VLAN 124 VMs to use a different VLAN, and update the addressing appropriately, it can access the Internet.
The problem is exhibited with Windows and Linux VMs. So, I believe something in my switch setup is the problem with VLAN 124 in particular.
If i do a show vlan brief, VLAN 124 is listed.
If I do a show ip int brief, VLAN 124 is listed as upup. I also tried to shut o shut the VLAN 124 interface.
Only one specific VLAN has connectivity problems?

View 2 Replies View RelatedScenario: Two buildings connected with a private leased fiber line, so it does operate as a LAN. There are several subnets and everyone at both buildings needs to be able to access all subnets. However the physical machines on those subnets are building specific:
-Building 1: 10.2.0.0/24 (vlan20), 10.4.0.0/24 (vlan40), Internet connection
-Building 2: 10.1.0.0/24 (vlan10), 10.3.0.0/24 (vlan30)
The majority of the traffic between the subnets is specific to the buildings as well (i.e. most of the traffic is between 10.1 and 10.3 or 10.2 and 10.4).
Currently I have a Catalyst 3560 at Building 1 operating as the single "core" L3 router (and then a variety of switches connected to that). I have another 3560 at Building 2 that I'd like to turn in to the "master" L3 router for the two subnets primarily used by Building 2. In other words, make it so traffic from 10.1 to 10.3 doesn't have to run to building 1 just to get back to building 2.
I've got a basic knowledge of adding VLANs, VLAN interfaces and a static routes. The part that I'm getting confused on is that the Building 1 core router needs to make its default route to the firewall (and on to the internet) but "know" that traffic on vlans 10 and 30 gets sent across the fiber line to the other router. So I'm assuming this gets done with some combination of vlan definitions, vlan interfaces and static ip routes on each router.
1. i have a few sites which are interconnected.
2. there are multiple mobile sets of equipment(servers and catalyst 3560 switch) which i need to connect at different sites. (i cant use repeated subnets)
3. i cant change the ip address/subnets/configuration of the servers and switch, when deploying at different sites. (big problem to me)
i was previously looking at IP unnumbered + OSPF to apply on the mobile sets of equipment. but noticed that IP unnumbered on non pt-to-pt interfaces (which happens to be a 3560) does not work with dynamic protocols. is there any solutions/alternatives which i can achive mobility on equipment?
I am currently deciding which IOS to use for various catalyst 3560 models. Version 12.2(55)SE3 seems fitting for this case, but I cant find out when the 12.2SE reaches End of Software Maintenance. I have checked this link: urls...
Where do I get info on 12.2.SE?
I am trying to implement static route tracking on a Catalyst 3560G ( WS-C3560G-48PS, IOS version 12.2(35)SE5 and SW image C3560-IPBASE-M). The configuration is as follows:
track 101 rtr 1 reachability
!
rtr 1
type echo protocol ipIcmpEcho 10.199.101.2
rtr schedule 1 life forever start-time now
!
IP address 10.199.101.2 is reachable via ICMP (its the next-hop router).
The static routes configured are the following:
ip route 0.0.0.0 0.0.0.0 10.199.101.2 track 101
ip route 0.0.0.0 0.0.0.0 10.200.52.1 20
But only the secondary route(ip route 0.0.0.0 0.0.0.0 10.200.52.1 20) its being installed on the routing table by the switch.
Assume I had Catalyst 3560X/3750X with 24 ports. The partnumber is WS-C3560X-24P-LI would like to how is the numbering defined if the switches have a C3KX-NM-10G installed with 4 SFP-GE-L.
View 1 Replies View RelatedI just recieved a new 3560-x switch with the C3KX-PWR-715WAC. It looks like Cisco is now using a different AC power cable. Not the StackPower connector, but the standard AC power cable. My data center is setup to supply 208v using C13 power cables. The switch uses a C15 power cable, and comes with a standard NEMA 5 to C13 power cable. Does Cisco make, or officially support a C13 to C15 power cable? Can I still use a 208v power supply with these switches?

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.

I'm configuring two etherchannel groups (2 ports in each) on a 3560 switch. I need to trunk multiple vlans over each channel group.
I created the vlan trunks and allowed vlans on each physical interface. I notice that I can also configure the vlan trunks on the port-channel interfaces that were created. Should I configure them under those interfaces, or leave them on the physical interfaces? Relevant config is below:
interface Port-channel1
