Cisco Switching/Routing :: 3560 - PBR Not Applying To SVI
May 12, 2013
We have two L3 3560's. One 3560 has an upstream MPLS router. The other 3560 has an upstream backup VPN router. Both of these 3560's are L3 switches with IP routing enabled. I created a PBR on both so that specific traffic routes through the MPLS router, while other traffic routes over the backup VPN router. I'm trying to apply the PBR to the SVI's, on each switch. However, when I do a "sh run", the PBR does not appear under either SVI. I've enabled the SDM Routing template, made sure that ip routing was enabled, and even verified that the IOS has the capability. Not sure what else to check for.
Quick question here. Using 3750E series switches with multiple VLANS configured. These switches serve as our 'core'. I have SVIs configured for the different VLANs and add inbound ACLs in each of the SVIs to control traffic between VLANS. This switch also terminates a P2P Ethernet link which connects to our Colo facility. The port used for this is configured as an L3 port. I noticed today that I was able to send traffic across this L3 link that I thought should have been blocked by an ACL I had in place but it wasn't. So the traffic flowed from a port in say VLAN 20 across this L3 link (assigned with an IP address). Would this traffic flow not cause traffic to be checked against an ACL applied in the inbound direction on the SVI of VLAN 20 (int vlan 20)? Traffic does get checked when routing between SVIs. Why would it not get checked when routing between SVI and L3 interface?
This isn't a big deal as the rest of the ACL works fine, but this is an annoynace since the web auth redirects to our company website (internal for now) after successful login.We have a Cisco WLC that provides access to our production and guest wireless environments. The guest environment of course is in a separate vlan (10.10.50.0/24). So I created this ACL:
access-list 107 permit udp any host 10.10.2.13 eq bootpc <----internal DHCP server access-list 107 permit udp any host 10.10.2.13 eq bootps access-list 107 deny ip any 10.10.0.0 0.0.255.255 <---all internal networks access-list 107 deny ip any 172.28.16.0 0.0.0.255 <----DR Network access-list 107 permit ip any any int vlan 50 Desc "Guest wireless network" ip access-group 107 in
This ACL basically gives the wireless guests access to an internal DHCP server and full access to the internet. For the 10.10.50.0/24 scope, the DHCP server assigns Internet DNS servers and my rationale is that wireless clients would access it via the external IP address but I suppose it doesn't work quite like that with the website being behind the same router as the client machines.
I have a situation where two of my CGS-2520-16S-8PC switches are not applying POE power to the copper ports, but showing power inline, two ports are showing power applied. Shutting down the port and re-enabling it will return the port to normal and the phone will connect.
I'm running cgs2520-lanbasek9-mz.122-58.EY2 after using 122-58-se1. Happening on both, but i have more switches running EY2 with no issues at the moment. Using DC power supply averaging around 53v.
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.
I am trying to get my workstation to talk to a workstation on a different sub-net through a Cisco 3560 switch. The switch is running the following IOS version: [code]
My primary network is 172.16.0.0 and I am trying to connect to a device on a 192.168.111.0 sub-net. [code]
What would be the best way to get the two workstations talking via the switch?
I implemented access list on cisco 3560 switch but it never works. I want to block access from network B to Network A and allow from Ato B Network A. 10.0.12.0/24 Network B 10.0.24.0/24
The configuration is interface Vlan1 description Data VLAN
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.
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 am trying to upgrade the IOS in 3560 but I am facing one issue. Its flash is 15MB & available space is 8MB whereas the IOS is of 11MB. How can I upgrade the IOS without upgrading the flash?
We bought a 3560 PoE switch to replace tons of PoE-injectors but when connecting the devices our logs were flooded with
Mar 11 15:09:20.725: %ILPOWER-7-DETECT: Interface Fa0/7: Power Device detected: IEEE PD Mar 11 15:09:20.725: %ILPOWER-5-INVALID_IEEE_CLASS: Interface Fa0/7: has detected invalid IEEE class: 7 device.

While the message seems quite clear im wondering if there's any workaround on the problem?
I have a Cisco SW ( 3560 ) with one Trunk link to my router ( 7606 ), Trunk link is fully utilized so i need to add 2nd Trunk.Shall all move some customers from old trunk to 2nd one and create a new subterface for them ?I am think if i can create bundle and add subinterfaces under this bundle ?Add two GE ports to be memeber of this bundle ?
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:
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.
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.
I've a question about QoS classification on Cat3560 From
"When QoS is enabled with the mls qos global configuration command and all other QoS settings are at their defaults, traffic is classified as best effort (the DSCP and QoS value is set to 0) without any policing. No policy maps are configured. The default port trust state on all ports is untrusted."
Now, when mls qos cos override is configured on a port, how is the switch behavior ? From documentation "All the incoming QoS values are assigned the default QoS value configured with this command". However I believe the port state is "untrusted".....so which DSCP values are assigned to them ? Is used a Qos-to-dscp map to derive the QoS label from the (overridden) QoS value also in this scenario ?
All switches are multilayer switches ( 3560) Pc1 and PC2 are running Cisco Soft phones. If we configure SW3 with: int f1/4 mls qos trust dscp.
1)Does the above command require SW3's f1/4 be configured as layer 3 port not layer 2? ( My reasoning is since Sw3 has to get to Ip header to process DSCP values, therefore Sw3'f1/4 should be configured for layer 3 operation.)
2) What if sw3 were not 3560 but layer 2 switch such as old 2900 series. can layer 2 switch be configured with: mls qos trust dscp.? Will layer 2 switch be able to interpret dscp values and perform QOS ? ( My understanding is layer 2 switch should not be able to read dscp values ). I will be posting few more questions on the above scenario.
I upgraded our 3560-48-ps switch from c3560-advipservicesk9-mz.122-35.SE5.bin to c3560-ipservicesk9.mz.122-55.SE4bin and is having issues now.
Since I upgraded to the new IOS our older machines on the network can no longer connect to the domain and is not getting an IP address sh ip dhcp binding and sh ip dhcp conflict does not show any output, however all newer machines on the network received dhcp addresses without any problems and can connect to the network and internet.
For testing purposes I put the old IOS back on the switch and the older machines could connect again and received dhcp addresses.No other changes were made to the config.
I did a comparison on Cisco's website and both IOS's support DHCP. Not sure why the new IOS would not give any output when I ran the commands.older machines : Apollos and NCS (They all have XP service pack 2 with Intel 2.8 processors.)
I have a need to use a 3560 switch to terminate a provider's internet connection, but want to secure it so that it and the vlans connected to it are not wide open. At the same time, I'd like to use stateful packet inspection.
I have IOS 12.2(44)SE2, but IPBASE running on my 3560s. Is there an IOS (perhaps the ADVIPSERVICES of that version?) that allows a 3560 to use the 'ip inspect' command?
Is there any way to check if this VLAN is used by somedevice?
Cisco3560#sh ip int b Vlan55 unassigned YES NVRAM administratively down down
Cisco3560#sh vlan VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active 55 Print active Fa0/5, Fa0/6, Fa0/7, Fa0/8
I have a 3560-48 switch running Cisco IOS Software, C3560 Software (C3560-ADVIPSERVICESK9-M), Version 12.2(44)SE3 and i need to implement basic QOS commands to the fast Ethernet interfaces as well as the gig interfaces and Also I need to create port channels on the switch and need what the port channel syntax are as well for that particular IOS version?
I have only read only access and i can't see what the QOS and Port channels syntax should be for that IOS version.
I am currently doing an audit at a customer site, i.e. am checking if any IOS upgrades are needed. I have found that alot of IOS versions that the customer is running are not available in the Cisco Software Download area anymore. Taking IOS 12.2(44)SE2 for the 3560 for example: some earlier and later versions are available as downloads, but this exact version is not. It also is not listed as a deferred version.What is Cisco telling us with this exactly? Are these "missing" versions not supported anymore i.e. is an upgrade to a supported version adviseable?
I have a 3560 connected to an edge device and I keep etting this error. I have turned off proxy arp and turned off ip cef under the interface, however I lot connectivity to the internet when I did that. I can't seem to find any documentation on this error. I understand what it means, I just don't know how to resolve the problem.
Would like to impliment VLAN's on Cisco IOS Software, C3560 Software (C3560-IPSERVICES-M), Version 12.2(25)SEB4...But I need a DHCP Realy to my Windows Based DHCP Server. How do I enable DHCP Relay on the 3560?
