Cisco Switching/Routing :: Set Management IP Address And Gateway On A 4500?
Apr 24, 2012
In mucking around with my 4500 I accidently deleted the ip address that I use to get into it with telnet and CNA. I have a console cable hooked up to and I'm in that way but the commands I got off the internet did not work. Those commands were set interface sc0 10.x.x.x/xx and set interface me1 10.x.x.x/xx. It didn't like interface and I notices when I did a set ?
I'm trying to figure out how to (or if I can) setup the management interfaces (fa1) on a couple of new 4500X switches. My issue is that the 4500X's themselves are the gateway for my management VLAN (.1 HSRP virtual, .2 and .3 SVIs on the pair of switches).
I would like to assign addresses from the management VLAN to the router Fa1 management interfaces but the software configuration guide seems to note this is not supported (and indeed it doesn't seem to work).
Physically I have Fa1 from core-1 into a port on an adjacent switch. Fa1 from core-2 also goes into a port on that adjacent switch. Both are in my management VLAN, whose SVIs are on the cores themselves.
It has ip helper configured that points to DHCP.From 4500 switch port - port x connects to 2960 port.Port x is configured as trunk between 4500 and 2960.
2960 config vlan 10 name data
All user ports are configured under vlan 10 and as access ports.Port x is trunk port connected frpm 2960 to 4500 switch allowing vlan 1 and 10 only.This switch has no default gateway configured.
We connected user PC on 2960 switchports and they were able to get the IP from DHCP server and were able to access the network? My question is how users on 2960 switch are able to access the network without ip default-gateway configured on 2960 switch?
We want to filter IP traffic by MAC address on Catalyst 4500. Since we are using bonding (active-backup mode) we need those mac addresses appear on different ports. Below are solutions that we have tried: ACL but it does not work since mac acls only match non ip traffic (We CAN NOT use ip acl). Use a static mac address-table entry to ALLOW specific mac addresses. It does not work either since the same MAC address needs to be seen on a different port. Catalyst 4500 does not support auto-learn option (as e.g. Nexus 5000).
Most of the 4500 Switches in our network are giving the similar error for so many ports
%C4K_L2MAN-6-INVALIDSOURCEADDRESSPACKET: (Suppressed 1 times)Packet received with invalid source MAC address (00:00:00:00:00:00) on p t Gi2/6 in vlan 100
Its impossible to do a wireshark packet tracing for all the ports.
We have a single 4500 connecting to two non-cisco devices. We need to enable port channelling or link aggregation between these two.The links are carrying mulitple vlans , hence are trunked and the ip address on either side is used for routing.
From each of the two non-cisco device, i am taking 2 ports each to connect to the 4500.On each non-cisco device side, two ports will bundle together as one aggregated interface (ae1) and the other will be called ae2.
my query is how do i do the configuration for etherchannel on the cisco 4500 side , as it will need two different Po's( port channels).I need a single ip address on both sides of port channel to be present for routing.
1 x 4500 and 1 x 3560?They are gateways of 8 Vlans?They are doing HSRP in each of those Vlans?The 4500 is the Active?There is a DHCP Pool for each of those Vlans on both gateways using "ip dhcp excluded-address" I ensured that the range of provided ips by each DHCP server will not be overlapped Obs.: Reducing the lease time, I ended with the calls bringing related problems.
OK, every thing is blue, every thing is fine.But the network diagram is realy complex(41 switchs, 89 uplinks), and depending of how is the network flow, one or other server answer first or latter.
For many reasons I would like that the secondary DHCP server would answer only if the primary DHCP server goes down.To me, the bigger reason is that DHCP database would be only in one DHCP server.But there is other reasons.
I passed by many frustrated solutions:Try to force a delay on the answer on one of the servers. - Impossible.Try to disable DHCP server, and, using EEM, enable it only if router became active in HSRP. - I couldn't do It.
What I'm thinking now is use the HSRP resource to resolve it.On both routers I would put a "ip helper-address" pointing to an Virtual_HSRP_IP.And depending on which router is the active, him will answer the request.
My first doubt is:Would it work?The second doubt is:Could I use the same Virtual_HSRP_IP that exists on that Vlan(see example 1),or I would need to point it to a Virtual_HSRP_IP in a different Vlan(see example 2)?
Example 1 ----------------------------------- | 4500 | ----------------------------------- interface Vlan1 ip address 10.10.0.2 255.255.0.0 ip helper-address 10.10.0.1 standby 1 ip 10.10.0.1
We have a server connected to a 3560 switch which in turn connects to 6500s. The gateway interface is on the 6500. We will be changing the 6500s so the mac address for the gateway will change, however the IP address will remain the same. As we change out the 6500s the uplink connections to the 3560 will go down. This will flush the old mac address from the 3560.When the 3560 removes a MAC address does it update servers so they have to relearn the correct MAC address?
As of late whenever I, or any of my roommates, browse the internet we have noticed a slower browsing experience, where pages used to load instantly, there is now a noticeable delay in accessing web pages. Also, in playing online video games, whether it be on the PlayStation 3 or PC gaming, high latency is always present. The problem is present whether there is one computer connected, or five, Mac or PC, Wireless a/b/g/n or if connected through the ethernet port. What I ask is: What causes such behavior, and what can I do, if anything, to resolve this issue?

Does the 4500 support VSS (Virtual Switching System) ? On the official product overview page it says: 1.6 Terabits capacity with Virtual Switching System (hardware-ready)What means Hardware ready ? Does it mean that it supports VSS in the same manner as the 6500 ? The reason I'm asking this question is that I didn't find any info on the Internet about this. We would like to upgrade our network by interconnecting the 2 sites with Layer 2 redundant links (Layer 2 extension), but I'd like to use the both links in a load-balancing manner, which can be a real pain in the *** with STP. The choice is between 4500 and 3750 stackable core switches. The 6500s are very expensive.
How to know 4500 SUP7-E's MIB ?Our customer use MS SCOM 2012 SP1 get the OID are 1.3.6.1.4.1.9.1.1286, but we use IOS MIB locator, we can not find this MIB id.
below are the IOS sh version information :

I've got a 3750X, IOS 15.0 IP Base license, reset to factory defaults, and I want to use the FastEthernet0 out-of-band management port on the backside next to the console port. The idea is that this port should provide a management interface that does not participate in the routing table. Problem is, contrary to the documentation, that configuring an IP address on the interface does make it show up in 'show ip route'. So it's still part of the routing table. Also, I'm unable to find the commands to change this and set a default gateway for just the management interface. I'm pretty sure this has to be possible, I remember seeing something similar on an ASA once. The 3750 configuration guide on Cisco.com does not seem to mention it.I considered using VRF but it's an IP Base license, no VRF.
What is the correct way to lic VSS on a 4500 SUP7L-E ? url... Under Table 5 - Support by Image Type; VSS is listed as available on IP Base (SUP7E only) and a plain Yes under Enterprise Services, inferring that you need Enterprise Services lic on SUP7L-E to get VSS? url...Under Table 1 - Minimum License for VSS; IP Base or higher (7-E) or special license (7-LE and Catalyst 4500-X)Can find no option on CCO / configuration tools to list a 'special' VSS license for 4500R+E chasiss with dual SUP7L-E and IP Base.How are you meant to purchase/license VSS on 4500E Chassis + SUP7L-E ?

How i can configure the SFP Ports on my 4500 SERIES CHASSIS with other SFP ports on the connecting switch. I want to connect 15 switches via GLC=SX=MM to my 4506E sfp card.
I am getting a very strange problem where 4500 switch is remarking the packet with dscp 1 to 0.
Let me explaint the setup. I have two PCs connected on same switch but on different modules. PC1 is conencted to Gi4/19 and PC2 is connected to Gi2/43. Both the ports has been configured to trust the dscp. Below are the configuration:
I am trying to setup the WOL for our enterprise. We have a C4500 setup with mutliple Vlans. We are using Microsoft SCCM server to wake up workstations for security update. The workstations are on vlan190 and the Microsoft server is on vlan 441
Here's my config
the config below
interface Vlan190ip directed-broadcast 100 (Enables the translation of a directed broadcast to physical broadcasts) access-list 100 remark ====== Wake-On-LAN ======no access-list 100 permit udp host 10.4.40.98 any eq 9 logaccess-list 100 remark ====== End of ACL 100 ======
We have 3 layer LAN architecture, layer 1 of 6500(IP routing), layer 2 of 4500(L2 switch only), layer 3 of 2960(L2 Switch)In a Single (2960 and 4500) Switch Port Avaya IP phone and PC are connected.Now, the requirement is that, Qos need to be configured for Voice traffic and Data traffic should be in default class of service.We plan to use COS value in Switch 4500 and 2960. We made a sample configuration as below
### For 4500 Switch class-map match-all VOIP-Access-2MB match cos 3 5 class-map match-all VOIP-Uplink-20MB match cos 3 5
[code].....
check these configurations are correct as per standard and if there is any other method of configuration?What need to be configured in L3 Switch(6500)??In 2960, it doesn't support ingress QoS, what impact it will make when compare to 4500? do users experiance any difference?
read the posts regarding vlans that are administratively down, they suggested that they are down if no ports are assigned to them, however I do have a switchport assigned, and the interface is still down. This is on the vtp server and on the clients. The vlan is not listed when issuing show vlan brief. Other vlans configured in a similar way do show and their interfaces are up. These are two Catalyst 4948-10G.Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500-IPBASEK9-M), Version 12.2(53)SG5, RELEASE SOFTWARE (fc1).
I have installed a WS-X4448-GB-RJ45 on a 4503 chasis. I could not get input or output rate, just shows 0 bit/seg wether or not is forwarding traffic. I would like to know if I have to make any configuration or workaround. The IOS version is 12.2(37)SG1.
When I connect two 4500-x switches in a VSS setup, do I need to have both 4500-x switches equiped with Enterprise Services, or can I mix IP Base with Enterprise Services in one VSS setup in order to save on licensing costs?
I have a Cisco 4500 Sup 6 engine and I have two 48 port fiber line cards installed. When I do a show interfaces I do not see any of the Fiber cards. This is a new out of the box 4500 and I installed the Sup 6 Line card in Slot #1, And the two 48 port Fiber cards in Slots 2 and 3. Am I missing something, is there a command or set up procidure for the line cards. I just assumed they were plug and play
I have a 4510R-E chassis which currently has a single supervisor 5 installed.
We are now looking at upgrading the supervisor to a Sup6. Now the question is this, can I install the Sup6 into the redundant cpu slot and then perform a failover to get the new switch working without any noticable downtime.
I'm not sure what having a Sup V and a Sup 6 in at the same time will do to the backplane.
Otherwise I have to take the switch down and then install the card and software manually.
I am about to configure 4 Gig ports for EtherChannel. I've been reading about EtherChannel and it seems easy enough to configure. I have a host (server)which I am going to connect to these 4 - gig ports. This is new for me and would like some feedback for those that have used EtherChannel on their layer 2 switches. The gig ports will be an access port with VLAN XX.
We are preparing to install a new switching Infrastructure at one of our sites. We have decided that we want to have two separate chassis as a core. My original idea was to purchase 2 - 4500 chassis and install 10Gb and 1GB line cards in each and use STP and HSRP to load balance between the two cores.
We had also contacted a vendor for thier recommendations and they came back with 2 6500 Chassis running VSS. I reviewed what VSS was as I had never heard of it and it looks to me basically to be real close to the same thing as Stacking. I didn't really want to have stacked Cores because I would like to have the flexibility to be able to take one core out and update the software or image, reboot, and such without effecting anything on the network. I can do that with the non-VSS approach but it looks like that would be more of a problem with VSS.
My question is, how to use VSS with the 6500's? How to take one of the VSS pairs off line and not effect normal network operations?
I have an in production x2 4500's which I would like to add a new vlan and IP address to.
