Cisco Switching/Routing :: Connect HP 420 Access Point To 4500 Switch
Apr 3, 2012
i am trying to configure my HP 420 access point. I have configure different SSID on it, This access point is connected to cisco 4500 switch, i have configure trunk on up link to access point.my problem is the client are not able to get an IP address form the correct vlan if i tagged the SSID to it.
in the following the output of show run int in cisco 4500 switch:
interface GigabitEthernet3/13

My actual Scenario
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

does it lead to high CPU utilisation as well ??

I have a Cisco 4500. Recently some of the ports seem to have "died"/ will not supply Poe to phones. Some work for data only. Other do not work at all. The switch has been restarted, this made no difference.

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?

We have a 4500 series switch that is running around 39% cpu utilization but seems to be dragging a bit. I did a show platform health and GalChassisVp-review has a target of 3% but an actual of 17%. All other actual values were at or below target values. I then went to show platform cpu packet statistics and in the "Packets received by Packet Queue" all queue packet values at 5 sec, 1 min, 5 min and 1 hour avg were either 0 or 1 with the exception of Esmp - that averaged 351/377/317 and 313 respectively. I then checked show platform hardware acl input entries static and the entry type InputEsmpToCPU had a whopping 10121370 hit count. All other entry types were well under that number.

I was checking some things on my Cisco 4500 and spot checking some of the ports. Using CNA it says it is at 10. The web browser to the switch says Full-duplex, 1000Mb/s, link type is auto, media type is 10/100/1000-TX on port 6i/18 The CNA says, so what would cause the difference?

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?

I have configured a SVI in my 4500 ( Sup 7-E 10GE,,,,,,and,,,,,cat4500e-universalk9.SPA.03.02.00.SG.150-2.SG.bin) switch and it is showing Down Down, because there were no active switch port in the vlan, I added one switch port to this vlan but this port also in the down state, so i added the SWITCH PORT AUTO STATE EXCLUDE command under this port, even after this also the SVI never came up, So i added one systen to the port so both the switch port and the SVI came up...So why SWITCH PORT AUTO STATE EXCLUDE command have no effect in this model of the switch..

I'm looking to implement a vlan filter to keep unnecessary stuff off my access-layer. Things like IPv6, IPX etc. I really only want IPv4, ARP and 802.1q on these 4500s. I know on 3750, 3560s etc, when I create the mac access-list, I can do it by ethertype, but on the 4500, I dont have that option.

On a 4500 switch port , defined as access vlan 10, if the user connects his own dhcp server ( instead of the normal pc that should be connected ), will it cause issues with my existing network. the existing network is all static ip. In above case, will the dhcp server start looking out and assign dhcp ip's , if a user unknowingly removes his static ip and changes to obtain ip via dhcp option on the lan properties.

I'm looking at provisioning a Catalyst 4500 with a WS-X4712-SFP+E module to allow for future 10Gb connectivity via 10Gb SFP+ interfaces. These cards are backwards compatible with standard 1Gb SFP interfaces but I'm wondering about the other way around; ie. can you populate these blades with 10Gb SFP+ interfaces when they connect to Catalysts with only 1Gb SFP interfaces at the other end?
The data sheets don't really explain this. It seems pointless getting 10Gb SFP+ interfaces for the 4500 when it's only 1Gb at the access layer end, but these access switches will be replaced in the near future (~12 months) and if the 10Gb SFP+ interfaces support connections at 1Gb speeds upfront, it would mean I could retain these interfaces when the access switches upgrade to 10Gb connectivity capabilities down the track. Does the 10Gb SFP+ interfaces are compatible with 1Gb SFP's or only other 10Gb SFP+ interfaces?

we have a 4510r-e running 12.2(50)SG1 w/ various rj45 line cards and a 24 port glc card.at any given time, i see 10's of ports in 10/full.i go to the station, and find the station in 100/full or 1000/full.
i go to the switch w/ my fluke, connect it directly to the switch w/o any intermediate infrastructure except a 50cm cat6 patch cable.the fluke reports 1000/full, but THE SWITCH PORT REPORTS STILL 10/FULL.all ports are config'd 'speed auto' and 'duplex auto'.
the switch seems to be erroneously reporting 10/full.there are no errors logged on any of the ports and there is successful communications even when the station and switch port report different speeds.even though there are no errors logged nor reported by 'show int [port]' nor 'sho int count error' certain killer applications crash on some stations. (the applications are GHOST (which dumps disk images from a server to multiple stations) and NETOP (which i sused in a classroom to transmit an instructors screen to a room full of stations) both of which broadcast and/or multicast.all nodes involved in the above 2 applics are on the same vlan and same phyiscal subnet.
the ports which report 10/full vary and occur even when the above applics are not in use.the only way i found to clear this 10/full report is by either a hardware reset of the entire module or by unplugging the cable, the execute on the port shutdown, speed auto, no shutdown, reconnect cable.then it's just a matter of time until it pops back to 10/full in a few minutes,hours or days.
how to address the killer applic problems besides restructuring the whole net by defining separate vlan for each lab of 20 or so stations?

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.

How do I connect and configure my WAP54G wireless access point to my new Cable Modem? I have it connected to the modem but I cannot access it to configure it. It appears to be working but before I got the cable modem I had it connected to a router and it was set-up with a static IP address. With my new ISP, I no longer have a static IP address so I am trying to configure the WAP54G to use DHCP. Trying to access it thru the internet at 192.168.1.245 does not work.

I've got a AP WAP54G. I've managed to get into the configuration page and rename my router and set a WPA2-Personl password.
The issue I'm facing is that when me and my roomate try to connect to the router at the same time, it shows the laptop that connects second as one that has 'limited connectivity' and hence cannot use the internet. The 1st laptop however works fine!
The settings for the router have all been left to default.
I'm not sure, but does this problem have anything to do with the fact that the router in configured with a static IP. If so, then there is another issure which is that whenever I try to change it from static to automatic/dynamic IP, the page fails and the router doesn't even get connected to the configuraion page(192.168.1.245) after that. The only way to get that page again is the reset the router.
Also I'm not able to directly get into the config page when I connect my router to my laptop via lan. I need to change the LAN IP to 192.168.1.x where x is >1.
