How to identify the OID to show the “total MAC Addresses In Use” on a 6509, This is the value we can see from a show mac-address counters, and I want our Solarwinds system to poll for it.

I have a solution of thre ACS.. one primary and two secondaries. My customer report me that in port of the switch where is connected the ACS show two mac address. [code]
View 1 Replies View RelatedI can see what MAC addresses have a wireless session and I've used MAC Filtering to stop some MAC addresses from using the network at certain times, but they are still getting through to the internet. I don't know if they were to clone their MAC address as to whether this would show up with the cloned address in active sessions list. How I can stop some users from getting through at certain times? Any utility I can use on my Mac (Mac OS X 10.6. to show which computers/MAC addresses are on the network?

View 3 Replies View RelatedConfiguring FWSM in a 6509. When I set "firewall vlan-group 40 40-42,251", it results in: "No more than one svi is allowed. Command rejected.".
I had "firewall multiple-vlan-interfaces" set for a previous use of this module, but took that off with the "no" command. Suspect that is the issue, but do not see how to resolve. Seems similar to bug CSCsr48563, but I am at the fixed code for that bug.
We have a design of two 6509 running in a VSS with dual supervisor each having fthree 10/100/1000mb etherner modules. We have diagnosed a wierd problem that none of the switchports in module 1 and 2 on either switches are having layer2/layer 3 connectivity.
Tried everything from changing the cables to changing the end device but no luck with it.
Module results show pass and no errors in the logging.
In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.
View 2 Replies View RelatedI have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

View 2 Replies View RelatedWe've (an independent school) just bought an SR520 with a view to replacing one of our Draytek 2820s. We need to set up some site-to-site VPN with NAT and the Drayteks won't do it.
I've been trying to configure the SR520 in just the most basic fashion using CCA (3.1) and the CLI but with no success. I can't get a PPP connection with our ISP.
I've tried following the instructions in the software config pdf and also tried replicating the various 'running configs' reported in other posts in this forum to allow connection to a UK ISP, with no success. I don't know how many times I've reset the poor thing to factory defaults.
I have to say that I'm dismayed at how flaky the CCA appears to be. Many of the things I've tried with it simply don't work and often end up in it hanging. Close to useless in my view.
So instead I've tried to use the CLI which seems a lot more solid but is somewhat impenetrable and there's precious little by way of supporting explanation.
Is it possible to increase bandwidth througput on 2951 router if you have 3 WAN connections from different ISP, lets say 12Mbps + 24Mbps + 8Mbps, so will I get 44Mbps internet connection in total?Also, on 887G router, if I use DSL 12Mbps broadband, can I use 3G internet connection constantly, not for backup only. And will I get the total bandwidth output as a sum of two connections?

I´m detecting on my ACE 20.
I´m monitoring the total number of concurrent sessions of my ACE 20 (using Cacti), and from time to time, with no discernable pattern, I see an instant drop of sessions to half...I don´t detect any disturbance with our traffic and service, I have no complaints, but it's a very accentuated drop.
I´m able to get 1 or 2 days withouth any suddent drop of connections, and then for no reason I pass from 500.000 to 200.000 sessions in a minute. Then they gradually go up again.
I´ve seen in ACE´s session table that she keeps a great number of half-open, or closed sessions, and those are counted as part of concurrent sessions. Is there any flush on ACE´s table when she reaches a certain number of closed TCP sessions or something like that?

We had several AIR-LAP1131AG-N-K9 devices have a peculiar failure recently.About 10 total units failed in groups of 2-4. Each group was on the same 3560 switch, and they failed at the same time.Now all but one of the units will power and work properly with an inline power injector. But they are either intermittent or not at all when connected to the POE Switch. Even when I use a 3ft patch cable to connect directly to the switch. I have certified the cable and they do the same no matter which port or cable used. 'show inline power' command will show these failed units as 'Iee PD'v

We're having kind of a problem with our Catalyst 4507r switches. If we do a "show interface" command we're getting a lot of "Total output drops" on some of our interfaces. It seems to be most of the time on the same vlan.I was wondering if it has got something to do with QOS or queue selection As we don't have any QOS markings configured, is it possible that all traffic is using only one of the four tx queue's?

We got a bunch of port-sec violations on port fa1/0/42. after checking logs, we noticed that the MAC address responsible for generating the alert was not one, but many.We asked the user, he said he only restarted his computer.The MAC addresses happen to be existing MAC on the network.How is it possible that a port-sec violation is made by many MAC addresses on the same port, successively?

When I try connecting via anyconnect the logs (and anyconnect messages) state the connection "cannot be established due to no addresses being available for SVC connection'". The group etc has a dhcp scope assigned, (and this was working for the past year). I'm not sure what config changes (if any) he made before leaving.
View 10 Replies View RelatedWe've never had a problem setting up ASA to ASA or ASA to PIX vpn site to site tunnels using RFC-1918 addresses ( 10.x.x.x usually ). Now we have a customer ( a hospital ) that requires a public non-RFC1918 address to be presented to them. Since the addresses that we send are routable, they get routed through the internet instead of going through the tunnel. Here's the boiler plate from the customer:
"Important Note: The following information is to be used as a guideline in setting up a VPN connection between XXXX and your organization. Currently, XXXX supports only site-to-site VPN’s and all partners MUST present valid registered public IP addresses through the VPN tunnel.XXXX is unable to accept RFC-1918 addresses (i.e. 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). We do not support PPTP, L2TP, or client VPN connections through a dialer application."
I was able to get a tunnel running between two ASA-5505 units using a public class C address that is currently not routable. How do I get this to work with a routable address? The tunnel will be carrying patient data and is basically a single server to single server link. It needs AES-256 and SHA-5 encryption but that shouldn't be a problem. The hospital is using a PIX, we are using an ASA-5510 with Security Plus license. We also have a couple of ASA-5505 units with base license to test with.
We sold an ESW 540 switch to a 3COM customer that is replacing old equipment. This replacement will be on different faces so we have to interconnect some 3COM switches to the Cisco equipment. We are installing rigth now and this two situations:
Virtual machines can´t get IP addresses via DHCP (using a different MAC address) when connected to the Cisco switch. Physical machines receive IP addresses from DHCP without problem. This situation never happened with 3COM switches.When we interconect the Cisco Switch to the 3COM switches (not using uplink ports) the connection never goes up. Remembering that 3COM switches are old we fixed the speed to 100 Mbps Full Duplex but it didn't work.
