Oct 24, 2011

i'd like to configure OSPF on a Catalyst 6503 IOS 12.2.17.i habe an Gi1/9 with the ip address 192.168.97.30/24 and a VLAN 19 with the IP Address 192.168.19.0/24.I configured OSPF like this
 
router ospf 1
network 192.168.97.0 0.0.0.255 area 10.5.0.0
network 192.168.19.0 0.0.0.255 area 10.5.0.0
 
on the ospf peer is see that the adjaceny is established but i don't get the routes for the 192.168.19.0 network i checked the ip ospf interface vlan 19; i got ospf is not enabled on the interface then i tried to configure

Cisco Switching/Routing :: Catalyst 3750X OSPF Support In IP Base Image?

Apr 3, 2011

I'm trying to work out if I need to order the "IP services" image for a couple of C3750-X.  I need to run OSPF on these switches, but find the IOS image requirements on Cisco contradict.
 
At the top of the data sheet it says: • Open Shortest Path First (OSPF) in IP Base image

On the product info page it says: IP Base: Enterprise Access Layer 3 Switching, including OSPF (Open Shortest Path First) for routed access 
 
But in lots of other places it says you need 'IP services' for OSPF.
  
As the IP services IOS is quite a bit more expensive I would like to avoid buying it. What image do I need to run OSPF?

Cisco Switching/Routing :: Nexus 7010 OSPF Passive-interface Default Not Showing

Nov 6, 2011

I'm currently working on a plan to migrate our 6500's over to our new 7010's.  At the time of the migration I want to tighten up our OSPF design and configure OSPF for "passive-interface default" then allow only those interfaces that should have OSPF neighbors to send the hellos.  The issue is that the command is not showing up under the OSPF process.  What's even more interesting is that the Nexus 5.x Unicast Routing Configuration Guide shows that the "passive-interface default" command should be an option to enter.
 
I'm currently running version 5.1(4) (though looking to upgrade to 5.2 during my migration testing).  I would rather configure the passive-interface via the routing process versus having to enter it on every interface.

Cisco Switching/Routing :: Migrating Cat 6503-E VSS To Cat 6509E VSS

Aug 7, 2012

I want to migrate a Cat 6503-E VSS to Cat 6509E VSS. We plan to use the same supervisor that we have on the Cat6503E, for minimizing the configuration change on the Doing this, the vss link will need to be changed, due to the fact that the supervisor slot will change with the Cat 6509, slot 5 instead of 1.

Question: is there a way to just change the vsl-link interface on a existing VSS ?

Cisco Switching/Routing :: 6503 Sup-2T Unable To Get Into ROMmon

Apr 11, 2013

I have an issue with a customers 6503 with Sup-2T cards, where we are locked out of the console due to an authentication configuration error. So tried several times to get the card into rommon, with no success.
 
Checking through the various documents on CCO I dont find any reference to rommon on this card, but do find information on using the CMP to support the supervisor. I logged into the CMP but couldn't find a way from there to do a password reccovery either.So, is the `normal' IOS rommon/password recovery method supported.

Cisco Switching/Routing :: Multiple VLAN Routing Tables For 3750 Catalyst

Oct 24, 2012

I have a network with a Catalyst 3750 as the main switch and then some Catalyst 2960 switches that are plugged in to that. I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?

Cisco Switching/Routing :: Catalyst 3750 Multi-cast VLAN Routing

Oct 28, 2012

I have a network with several catalyst 2960 switches and one catalyst 3750. I have created two VLAN and set up the proper routing and everything is working fine there. I have a client/server application that used multicast in the initial start up for the client to determine available servers, the issue is one of my clients is on a different VLAN then the server. I am able to route the multicast using MVR as long as both the server and the client are plugged into the 3750 by creating a static route, making the server a source port and the client a receive port. Unfortunately I need the client and the server plugged in to different 2960s. My question is how do I establish multicast routing between the two and perferably do it dynamically (always route multicast traffic from one VLAN to another).

Cisco Switching/Routing :: Inter-VLan Routing On Catalyst 3750 Switch

Dec 17, 2011

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
 
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
 
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to  (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet.  I think it has to do with the routes.

Cisco Switching/Routing :: VLAN Bridge With Catalyst 3750

Nov 8, 2012

I have 3 VLANs here that need to be on the same network segment.  They are going to be used by our Wi-Fi network (with Aironet APs), bound to 3 different SSIDs (as Aironet APs doesnt allow multiple SSID per VLAN), each one with a different authentication method and server.Is there a way to bridge those VLANs together with a Catalyst 3750 switch?  I tryed configuring an IP address on one of the VLAN interfaces, then configuring a bridge with the vlan-bridge protocol (Catalyst 3750 doesnt have the "ieee" bridge protocol type) and put all 3 VLAN interfaces on the same bridge-group, but it didnt work (even with "bridge x route ip").I also tryed configuring IRB bridging, with the 3 VLAN interfaces on the same bridge-group and an IP address on the BVI interface (the way I used to do with old 2600 routers).  Same result.(actually, I didint test to see if the interfaces are actually being "bridged", but I see neither of them can reach the router)

Cisco Switching/Routing :: Catalyst 6509 Interface Alarm?

Now I am at site trying to identify and diagnose this fault.Looking at the numbering on the switch, it indicates to me the card where these alarms come from is from the 'intrusion dectection module'

how I may login and identify this interfaces and rectify these alarms.

Cisco Switching/Routing :: Catalyst 2960 - Get Notconnect On Interface

Nov 20, 2012

At one of my sites, I have a 100mbit TLS. For this connection to work properly, the port on my end needs to be setup for 100mbit, full duplex. When I connect the TLS to an interface on my Cisco 2821, configured at 100/full, it works perfectly. Now the confusing part, I'm trying to connect the TLS to a Catalyst 2960. I configure the necessary port for 100/full, and get 'notconnect' on that interface. I set the interface to auto/auto, and it negotiates at 100/half and causes collisions and packet loss.

Cisco Switching/Routing :: Configure Inter-vlan On Catalyst 3750

Dec 20, 2012

My architecture is the same as show on the link with some difference.I use the router 1841 for inetrnet connexion instead of 7200VXR, this router 1841 is connected on the catalyst 3750 port G1/0/1.I use catalyst 2960 instead of catalyst 2950 or 2948.I use ASA 5510 for conexion on remote branche(I have 5 remote site), This ASA is connected on the catalyst 3750 port G1/0/37
 
Result of the test:

-I can ping devices in the same Vlans
-I can ping devices in different VLANs
-I can ping all device from the catalyst 3750
 
I cannot ping the router 1841 or ASA 5510 from the any devices (computer)The gateway of each computer is the correpondant VLAN IP address configured on the catalyst 3750.Why I cannot ping the router 1841 or ASA 5510 from the any devices (computer)

Cisco Switching/Routing :: Manipulating VLAN Quickly On Catalyst 3550

Dec 12, 2011

I am attempting to create a mass upgrade server for some of our more standardized equipment since our vender cannot upgrade them pre-shipping for us, we've got to do them on our own. This means using a terribly organized wizard written in what appears to be Java...
 
I have an aversion to Windows and felt that I could accomplish the same thing using expect scripts and a Gentoo Linux server; now all I need is to set my Cisco 3550 (c3550-ipservicesk9-mz.122-44.SE6.bin) to have each port on it's own VLAN, except for fa0/1 which will be a trunk port to communicate with all ports as well as the server.

Cisco Switching/Routing :: Catalyst 6506 Vlan-based Qos Configuration?

I was unable to configure vlan-based qos on Cisco IOS Software, s72033_rp Software (s72033_rp-IPSERVICESK9-M), Version 12.2(33)SXH6, RELEASE SOFTWARE (fc1) Seems to me my configuration is not working. Here is the output of the interface:
 
sh int G1/6 | i rate
Queueing strategy: fifo
30 second input rate 25231000 bits/sec, 4282 packets/sec
30 second output rate 46940000 bits/sec, 9257 packets/sec
 
And here is my configuration:

ip address 192.168.1.1 255.255.252.0
service-policy input TEST_IN_PMAP
service-policy output TEST_OUT_PMAP

[code]....

Why I can't see matches in ACLs? I've double checked the direction and seems to me it is correct. I can't see matches even I configure something like this:

10 permit ip host 192.168.1.168 any 
20 permit ip any host 192.168.1.168

Why my output rate is higher than 30M? Is it bacause there is no matching traffic here in ACLs? I'm absolutely shure that this host with such ip connected to this interface:

#sh arp | i 192.168.1.168

Cisco Switching/Routing :: Catalyst 2960 / VLAN Configuration Using MS DHCP Server

Jan 28, 2013

I am going to creat VLANs very 1st time therefore for test purpose I have following simple scnerio.I have created 2 VLANs , VLAN2 and VLAN3 on Cisco Catalyst 2960 series switch. Ports 1-12 is assigned to VLAN2 and Ports 13-24 are assiged to VLAN3. Now I have configured DHCP on Microsoft Server 2003 defining 2 scopes with following configurations.
 
Scope 1 for VLAN 2--- Range is 172.16.0.17 to 172.16.0.30   with subnet mask=255.255.255.240 . Server IP address 172.16.0.17
( Note: Address 172.16.0.17 is excluded from dhcp server Scope 1 and give to the MS server itself)
 Scope 2 for VLAN 3----Range is  172.16.0.33 to 172.16.0.46 with subnet mask=255.255.255.240 .
 
Now in Cisco 2960 series switches, under Vlan 2 and Vlan 3, I have following configurations...
 
interface Vlan2
ip address 172.16.0.30 255.255.255.240
ip helper-address 172.16.0.17
 interface Vlan3
ip address 172.16.0.46 255.255.255.240
ip helper-address 172.16.0.17
 
Now the problem is when i connect a client computer to any port from 1-12, It gets correct IP address from Scope 1 but when I connect a computer to any port from 13-24, it does not get the ip address.
 
Further I want to do inter VLAN comunication as well for that purpose i Have an  ISR 2900 series router. What further configuration i will have to do on router for inter vlan communication.

Cisco Switching/Routing :: Catalyst 4505 - Write Extended ACL For Voice VLan

May 14, 2012

I am trying to write an extended ACL for the voice vlan.My scenario is the following:I have two PBXs with two Catalyst 4505 L3 switches.The C4505 are connected trough a trunk link.I have a VTP domain configured.

Voice VLANs are Vlan 100 and Vlan 101 with networks 10.2.0.0/16 and 10.4.0.0/16 Voip telephones are communicating between them self and everything is working fine.I want to secure both voice VLANs with an ACL to allow only couple of IPs to administer the phones.The PCs are connected trough a integrated switch via VOIP telephone.Here is the sample configuration of the dhcp pool for the PC VLAN:

ip dhcp pool PCs
   network 10.1.0.0 255.255.0.0
   default-router 10.1.1.1
   dns-server 10.10.10.1
   option 43 hex 010a.5369.656d.656e.7300.0000.0204.0000.0064.0000.0000.00ff

I had to implement the 43 hex option because the PCs did not get the ip from the DHCP because of the vendor specific information.The thing that worries me is will the DHCP forward the ACKs for the PCs if I implement this test ACL:

ip access-list extended VLAN100
permit ip 10.2.0.0 0.0.255.255 10.4.0.0 0.0.255.255
permit ip 10.4.0.0 0.0.255.255 10.2.0.0 0.0.255.255
permit ip 192.168.2.0 0.0.0.255 10.2.0.0 0.0.255.255
permit ip 192.168.2.0 0.0.0.255 10.4.0.0 0.0.255.255
permit udp host 0.0.0.0 eq bootpc host 255.255.255.255 eq bootps  (this I am not sure do I need)
permit udp host 255.255.255.255 eq bootps host 0.0.0.0 eq bootpc   (also this)
deny   ip any any
 
I only want to allow the network 192.168.2.0/24 and maybe some other hosts to access the web based http gui to adiminister the IP phones.All PCs are connected trough the VOIP terminals. I do not want to deny the traffic to PCs.
