There is some way to increase the speed of changing the interface state from DOWN to UP when the cable is connected. I need to configure a port of Cisco 4503 in a way that when a cable is connected the port goes immediatly UP.
A solution can be to keep Cisco interface always UP and I remember that with "no keepalive" command to the interface configuration it was possible. But I tried and nothing happens.
Here's my problem. I'm going to be using Cisco 1941 routers at a bunch of remote sites. All of these sites have 2 comm paths out. Some of them have 2 IP/VHF radios and some have 1 IP/VHF radio and a copper link using Patton ethernet extenders. From the VHF radios the data hit our MPLS network back to our HQ and the sites with copper go directly back to our HQ. Everything ends up at a Cisco 4948 switch. The problem I'm having is that I want the routers at the remote site to use one ethernet port (G0/0) as the primary and the other (G0/1) as the backup interface. I've tried the backup interface command but the problem is that depending on where an outage occurs the ethernet link to either the radio or Patton stays up so it never switches over. We're using OSPF as our routing protocol and I'm sure there's something that can be done with it but I'm not sure what.

I am trying to connect a 6509 switch to a 4503-E switch using single mode dark fiber over a distance of less than half a mile. Although a routine task, it does not work..We have a care 6509 switch where we concentrate all of our dark fiber connections for our remote sites. The 6509 switch already has 30 remote sites, most of them with 4503-E switches, connected in this way therefore it is a tested scenario. For the connections we use the GLC-LH-SM SFPs on both switches. Out of these 30 sites we had a similar problem with two of them, which we solved with the use of CWDM SFPs. With the CWDMs the fiber came up right away. However, I cannot keep using this solution because it is way too expensive! I had the losses of the fiber measured end-to-end and they are negligible (>0.5 dB).
In this latest case, like I said, we could not bring the connection up between the core 6509 switch and the 4503-E switch using the GLC-LH-SM SFPs. I then replaced the 4503-E switch with a 3560 and the link came up! Then I tried using a CWDM-SFP in the 4503-E, while keeping the GLC-LH-SM SFP in the 6509 and the link came alive again! Of course we already tried replacing the fiber patch cords with no luck. [code] I find it very weird for the link to work with the 3560 or with a CWDM in the 4503 but NOT with the SFP in the 4503!
I have a 4503 switch (in L2 mode) running 12.1 hooked into a C2950 running 12.1, using regular 4 pair Cat5e cables to connect between them. The 4503 has Gigabit port 2/1 trunking to the 2950's Fa port 0/13.
When I set the duplex mode to DUPLEX FULL and SPEED to SPEED 100 on both switches (for their trunk ports) the link fails, and my 4503 loses connectivity (since it gets it from the 2950).
Here is my config from the switches (per description):
The 4503:
interface GigabitEthernet2/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,100-140
[Code].....
Note, this is the only mode that works (which seems to work fine, but I get TERRIBLE throughput for anything that goes over the 2950.
Currently we have cisco 4503 switch in one of our location without redundancy which servers below,

View 6 Replies View RelatedWe have a gateway on a 4503, say on port 2/1, and we only want the other devices that are plugged into the 4503 to be able to talk to the gateway and thats it. The other devices are Motorola TUT DSL devices and they plug into the 4503 directly.
Normally "switchport protected" would make this very easy to keep stuff on one port from talking to other ports but with 4500's you are not able to do that command. So we implemented a MAC Access-List Extended ACL. Here is what we did
mac access-list extended BLAH
permit #host 0000.XXXX.YYYY any
interface range fa 2/5 - 20
mac access-group BLAH out
The MAC address 0000.XXXX.YYYY is the MAC address of the gateway that is plugged into Fa2/1 and the DSL TUT devices are plugged into ports Fa2/5-20. We would think that this config would only allow devices on the TUT DSL to talk only to the Gateway but we don't really think this is happening. The TUT devices are learning about MAC addresses that are on other TUT devices.
Do the cisco 4503 switches support virtual clustering feature ? I have a requirement where switch ports on two different 4503 switches need to combined in the same Link aggregation group . This is needed because the firewall notes say that the aggregated interfaces need to be conected to a single switch and combined in the same LAG . So according to the diagram below , the interfaces marked RED need to be in the same LAG in the switches , same for the interfaces marked BLUE . I have done the same setup using Juniper switches where it uses VIRTUAL CLUSTERING to group the different switch ports in the same LAG.

We had a core switch (4503), distribution switches and access in our network and consists of many vlans. Almost all vlans uses DHCP Pools. But for few vlans DHCP is not yet configured. Recently one of the rogue user in vlan 1 gave the corresponding interface vlan ip of core switch (gateway) as his ip and caused a prolonged network outage for the vlan. Any way we are going to seggregate vlan 1 into different vlans, but before that we need a temporary plan to block such kinds of attack.What are the possible ways we can avoid the network outage problem even if a user gave the gateway ip to the machine?

I curently have 2 Data centers connected with a Metro Ethernet Connection. Each Data Center has 6500 with Sup720s. The Metro Ethernet connection is currently conected by a L3 routed interface. I now need to enable VRFs between the locations and want to determine the best way to adjust the Mero. I was considering adjusting the routed interface to use Ethernet sub-interfaces. Each VRF would be given a different subinterface over the Metro Ethernet connection. I have done this on internal LAN connections but am concerned about exteding across data centers over Metro E.

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?

I own a Cisco 892W router. The router has 2 WAN ports and 8 switch ports. Now I know -
-WAN ports can create sub interfaces, assigne IPs, cannot be assigned to a VLAN - sounds very much like a routing port. (sh interface gives - Hardware is PQII_PRO_UEC)
-Switch ports are for VLAN assignment, trunking, IP assigment etc,. (sh interface gives Hardware is Fast Ethernet)
I know they are different but at the same time confuced what the difference are? I also know on some 3xxx series switchs you could say "no switchport" and translate a switch port to a layer 3 port. But on 892W you can't do this? Struggeling to understand the difference.
