We have created more than 255 Vlans during last 5 years, and we know that eye-catching part of which are unused, I took a report from campus manager searching for Port Attributes to find out which port is assigned to a specific Vlan but as long as there are numerous ports in trunk mode connecting to Virtual servers I can not find out if unused vlans which I exclude from the report I took are really unused or not , how can I find the unused Vlans.
I have PIX 535 and using ACLs for allowing traffic. I need to clean up the rule base. I would like to know how to fetch a report of Unused rules for long time?Also when a traffic is being allowed, I want to know through which rule number its being allowed?
I've configured the DHCP server on a Cisco Switch C3560E as follows:
ip dhcp excluded-address 172.16.0.1 172.16.10.255 ip dhcp pool perth_main network 172.16.0.0 255.255.0.0 default-router 172.16.10.254 lease 0 8 !
My goal was to limit the dhcp to the range 172.16.11.0 - 172.16.13.255, as there are not so many user on this network I so limited the lease time to 8 hours in order to "recycle" the unused addresses". What happend is that it is always using new IPs, even if the lease time has expired.
IP address Client-ID/ Lease expiration Type Hardware address/ User name 172.16.109.90 XXXXXXXXXXXX Apr 04 2013 10:00 PM Automatic 172.16.113.106 XXXXXXXXXXXX Apr 04 2013 06:55 PM Automatic 172.16.113.122 XXXXXXXXXXXX Apr 04 2013 09:04 PM Automatic
[code]....
1. How can I force the DHCP server to recycle the unused IPs?
2. Can I specify a DHCP range (172.16.11.0 - 172.16.13.255) instead of an "excluded-address" range?
I have a pair of ASA 5540 running 8.4 code. The firewall set has about 4500 rules. I am tasked to identify all unused/idel/inactive rules in the past 3 months.
I was just checking my router's firewall log and I noticed a couple of entries which appear somewhat suspicious, amongst all the 'normal' background radiation of (mainly) Russian and Chinese IPs: [code] The source IP for these 'attacks' is/was unused on my internal network.
My router is a Billion BiPAC 7800N running 1.06e firmware. There are a number of devices permanently connected to the internal network and a number which are connected at other times (e.g. desktops, laptops, mobile/cell phones, games consoles). Some are wired, some are wireless. Some have static IPs (none of which are listed in the above 'attacks'), some have dynamic IPs (assigned by DHCP by the router in a range not listed above). The WiFi is secured with a strong key on WPA/WPA2-PSK, AES (no WPS). Web Access Control for the router is disabled. Block WAN PING (and Block WAN (IPv6) PING) are both enabled.
I had the 2 circuits go down at the same time from our ISP and I had to power cycle the router and when it came back up I went from VA # 2 to now VA 3#....I know what is what but it is confusing for my counterpart and I can not remove the old entry for VA#1 and VA#2. [code]
Just replaced a WRT54GS with an E2500. It seems that anytime a connected device goes "idle" for a while, the connection breaks or severely reduces and it's nearly impossible to get the connection back without performing an action at the device in question. Let the wireless connection on my laptop go unused for some period and it reduces to 1Mbps and you can't get back on by just using the link more... you have to do a "repair".
Let more than a few minutes pass since you've printed something on the wireless printer and you MUST go to the printer to re-establish the connection by turning the antenna off and then on again.Basically the same problem with my blueray/DVD getting on the network. When I shut the screen off on my phone, the wifi dies and receives NOTHING over that link while the screen is off.
None of these behaviors existed with the WRT... just the 2500. Background/facts - current firmware, DHCP with reservations, WPA2/per, MAC filtering in use, UPnP disabled. MTU/Beacon/Frag threshold/RTS threshold set per recommendations on this site.
WE have to deploy ASA5585 in between User vlans & server vlans. we have to find all the ports that needs to be opened on firewall. any tools to do same.
Is there a free version of a program that would allow to find out an IP address of a person on an IM (gg, msn messenger and others)?Is there a firewall I could use for this? [URL]but it doesn't seem to work...? To access image log you need ... file name, folder and password. For file name do I put extension too? and for folder what do i put?
I bought 2 WAP4410N wireless routers but it did not come with a PoE injector. We do not have a PoE capable switch. I have a couple of 3COM PoE injectors but am concerned about differing PoE standards could cause the 3Com PoE injector to damage the WAP4410N.
I cannot find a PoE injector on the Cisco website. What is the Cisco part number for a PoE injector for the Cisco WAP4410N or provide assurances about the 3COM PoE that I have for the 3COM 3CRWER100-75 access points?
I need to find the headers of different protocols like ETH_IP, ETH_IPv6_IP, ETH_MPLS_IP, ETH_VLAN_IP , ETH_MPLS_ETH_IP , ETH_MPLS_MPLS_IP, PPPC_IP_TCPnUDP and many more.
I dnt know how to find. some one told me about wireshark , i installed that software and started capturing the packets but didnt find any of above except ip.
I recently had to clean up a laptop of a few years worth of crap and no protection on the machine.i had to do the disk clean up in safe mode as it ran far too slowly to do anything without a monumental level of patience, the problem i have now is that the computer doesnt seem to be picking up the wireless network around the house even though other units laptops are working fine.
I have a Dell Inspiron I got last July that has Windows 7.It had been working well but the started to say there were no Wifi signals.. when I knew there was from the other computers and such. I would start up diagnosis and it would fix for say half hour, then I would do it again and each time only for a short time, reducing each time. The same happened when I disabled or even deleted and reinstall programme the wifi adapter (which it always had a pop up saying it didnt do it properly).It also keeps saying to plug in to wifi which works but doesnt solve the wifi issue.I even had my father in law who was an IT guy look at it and no clue.I am desperate to get it fixed as I have lots of assignments to be getting on with.
I am looking to port legacy ACS 4.2 "proxy distribution tables" to ISE 1.1.1 and I am currently a little at a loss where to start. I know I have to add the External RADIUS Server, Configure a RADIUS Server Sequence that will skip local authentications then send to the External RADIUS server. How do I match this authentication and how do I match it to an authorization rule? Is this the Network Access:Use Case equals proxy?
I have got my WRVS4400 setup and i can VPN into the network. Once in i cannot access any of the computers inside the network. I can log into the router and see that they are connected but I cannot find them in my windows network.
I was looking an HWIC card for CISCO2901-SEC/K9. We have one internet connection (ADSL) current.Now we want to backup internet connection from cable service provider. I will implement IPSec on this HWIC.
I am using a Linksys WRVS4400N V1 running firmware 1.1.08 and although generally performance is good there are a few issues which I was hoping a firmware update could fix, however I cannot find it anywhere on the Cisco website.
I am doing a security course and I need to find out the IP addresses of the devices on my network in order to carry out a ping of death on one of my devices. I've done the ipconfig command but that doesn't give me the information I need.
I have had to re format vista and reload my WiFi. My internet connection using an ethernet cable to my LAN works ok but when the ethernet cable is removed and I click "connect" I am asked for my security key or passphrase. How do I find this information or preferably remove the request for it?
My laptop isn't finding any wireless connections, it's a hp windows 7. I also have a toshiba satellite laptop currently connected to the same wireless connection that the hp is not finding.
Friend has an older 2wire home router & has no idea what the security key is to allow me to add my laptop and work at her house. How can we retrieve it.
