Cisco Switching/Routing :: Catalyst 4500 As Layer 2 Switch But With VRF?
Oct 16, 2012
is it possible to run a Catalyst 4500 as pure Layer 2 Switch, i.e. disabling "ip routing", but still managing the switch via Fa1, i.e. the defautl mgmtVrf vrf ?I tried the following:
!
no ip routing
!
interface FastEthernet1
ip vrf forwarding mgmtVrf
ip address 192.168.1.1 255.255.255.0
!
ip route vrf mgmtVrf 0.0.0.0 0.0.0.0 192.168.1.254
ip default-gateway 192.168.1.254
I was not able to reach the Switch even from the same subnet. Only after enabling ip routing I could manage the Switch. I haven't found any command to set ip default-gateway for a vrf. Any workaround to keep routing disabled, but still manageable via VRF?

4500 switch is connected to 2960 switch.
4500 config
Vlan 10
name Data
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?

Do you have the ability to setup DHCP servers on this layer 3 switch? I know I can with my old 3550 switch. Want to upgrade and make sure this model supports setting up dhcp servers on it.

I have seen links out there for a conversion tool to convert commands on a Catalyst type switch (6509) to newer IOS type switches(4500-e) switches but they all error out on me on a 404. Any link where I can get this conversion tool?

tore down config
tried second set of interface
int t6/1 - int g8/17 1 Gig fiber link
Ping successful

We are about to install a new network consisting of Cat 4500s with Sup7E at the Access Layer, with Nexus 7000 at the Distribution and Core layers. We have 14 floors with at least three 4500s on each floor. Within the office block where the Access Layer and Distribution Layer reside we need to support secure borderless networking using 802.1x to place users from different parts of the business into segregated networks at layer 3.All switches will have the feature sets to support MPLS/ VRF / OSPF / EIGRP / BGP etc.We quickly dismissed the idea of using VRF-Lite due to the sheer number of Vlans we would need to managage and maintain, the point to point links alone just to get one additional VRF on each floor required far too many Vlans.As a result we are now considering deploying MPLS. The obvious benefits include scalability and manageability, the fact that all switch to switch links can now be routed, instead of having to using SVIs.

I've been conducting research on configuring 3 distribution switches in my network which are Cisco Catalyst 4507's to communicate with our core over layer 3. Our core switch which is already configured at Layer 3 for intervlan routing is a Cisco Catalyst 6509.
I've got the configuration portion complete and all devices are able to communicate my only question is about QoS. Do I have to configure QoS at the layer 3 interfaces for voice, if so how is that completed. We have several vlans and separate the vlans for each building by voice and data. We only configure ports on the access switches with voice vlans for QoS and we use the auto qos option on these interfaces.

I've two Cisco 4500 running as core switches for huge and complex network. The two 4500 are going to act as dhcp server for several subnets. The easiest solution would be to split each DHCP pool in two, and assign the first half of the pool to one of the core switch and the second half of the pool to the second core switch. This would be a partial solution since if one of the two fails, the second core switch would not have enough dhcp leases available for all the devices connected for each subnet.For such a reason, I'm wondering if it the 4500 switches support a stateful redundant DHCP servers, so that the two switches can synchronize their DHCP lease tables. If this feature is available, I could define the same pools for both the switches without the risk of having duplicate ip addresses within the network.

We have a Switch Catalyst 4500, model WS-C4510R+E, with 2 Supervisors, models V-10GE, which is showing high CPU values all times.When this occures, the switch shows 95-100% for total cpu for a few hours at a time.show proccesses cpu shows process Cat4k Mgmt LoPri with an unusual cpu value of 56% The show platform heath command gave me a high reading for K2L2 Address Table R which is curently 9,45% but the last hour is around a 20% average CPU ?[URL] what the process K2L2 Address Table R means and what could be the cause of this peak?

I was reading the documentation of the Catalyst 4500-X for creating VSS and MEC (multichassis etherchannel).In the VSS specific part, it's written"Cisco Release IOS XE 3.4.0SG does not support Layer 3 MEC".
Can I still use VlanX interfaces ad route through them?In my setup I only have IP addresses assigned to vlanX interfaces (with some VRF-lite magic)[code] Does that sentence only mean that I can't have IP assigned directly to the MEC?

On 45XX catalyst , bandwidth is allocated across six 8-port groups, providing 1 Gbps per port group. Example for the following line card : WS-X4448-GB-SFP
I want to know if there is the same mecanism on 3750X switches. I mean is bandwidth allocated across a group of ports like on 4500 catalyst ?

If I'm upgrading dual redundant power supplies in a Catalyst 4507 from 1000W (data) to 1400W (data), can it be done without taking the switch through a power cycle? I'm guessing no as I read that the switch will not recognize a 1400W PSU in bay 2 if there is still an original 1000W PSU in bay 1.

I just received a new 4510R+E switch with CAT4500e SUP7e Universal Image cat4500e-universal.spa03.01.01.sg.150-1.x01.bin software imag with License Level ipbase. We specified in the order to receive CAT4500e Universal Crypto Image with License Level ipbase. I have since requested and received the latest CAT4500e Univeral Crypto Image cat4500e-universalk9-spa.03.04.00.sg.151-2.sg.bin. Is there anything other that just installing the new image that must be done to allow me to use the Crypto Image? Would this upgrade do anything to change my License Level ipbase?

Does a new Cisco Catalyst 4500 series supervisor 7L-E model WS-X45-SUP7L-E is backward compatible with a Cisco Catalyst 4500 series chassis model 4507R? I've checked on Cisco website for that Supervisor and it shows only new chassis models WS-C4507R+E and R-E, but what about old type of chassis? We need to upgrade that Supervisor as it's out of line, but we don't really want to buy a new chassis as well as it's going to be very pricy.

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).

I found a bug in Embedded Event Manager, on Catalyst 4500-E platform with supervisor V-10GE, on various IOS releases (in particular 12.2-50-SG IP BASE w/o crypto, 12.2-54-SG1 IP BASE w/o crypto, but also other releases included latest 15.0-2-SG1 ENTERPRISE SERVICES SSH).The problem is that when you set up a EEM applet that monitors syslog pattern matching, and you also configure remote host logging *with* the option "sequence-num-session", when the match occurs, the switch reboots with message:
Sw (sometimes prints a number instead)
VECTOR D00
and in some cases performs a second reboot with message:
VECTOR 0
DOUBLE FAULT
The reload reason message is:
System returned to ROM by abort at PC 0x0
The problem does *not* occur if remote logging has not the option "sequence-num-session". I verified this behavior on various configurations (included our production 130K long *and* factory defaults after erase startup-config).The configuration statements that cause reload are, for expample:
event manager applet prova
event syslog pattern %SYS-5-CONFIG_I
action 1.0 puts "configurazione modificata"
!
logging host 172.30.10.1 sequence-num-session
