I have bridged several w/l Tranzeo's together. I have given each of them an IP address on the same subnet as my gateway and manage the units using that addressOther than for management is the IP address of a bridge used for anything else? I have noticed that I can plug in any gateway address I like and the units are perfectly happy even if the phoney gateway does not exist.

View 2 Replies View RelatedI have a remote site that has an AP running in H-REAP mode which connects over our MPLS cloud to a WLC, which has one interface on the "inside" network and one on our DMZ. The remote AP in H-REAP mode currently only runs our Guest SSID, but now I need to established an isolated VLAN.
Two of the hosts on this isolated VLAN, which is need to support some conference room devices, need to run on wireless and communicate with two devices on the same VLAN that are hard-wired to the switch.
Getting the wireless devices to connect remotely is easy enough by setting up an SSID that uses an IP subnet which one of the WLC's interfaces actually connects to...but can I do that for a completely remote IP subnet (i.e. one that the WLC does NOT physically connect to?). I'm not sure and I'm wondering whether that's the purpose of the "Remote LAN" feature...which is a very new feature.
I really need understanding some of the logic behind the default ZBFW settings on my Cisco 881W courtesy of Cisco Configuration Professional. Here are my two questions:
1.) What is the purpose and logic behind consolidating the first class-map (ccp-cls-insp-traffic) in to the second Class-Map (ccp-insp-traffic) as follows?
Code ....
2.) What is the purpose and logic of Policy-Map ccp-inspect is trying to drop traffic from ccp-invalid-src, which is filtering based on ACL 100:
policy-map type inspect ccp-inspectclass type inspect ccp-invalid-src drop logclass type inspect ccp-insp-traffic inspectclass type inspect ccp-protocol-httpclass class-default drop.

I have a Dell R300 server and it does not have a separate DRAC card. When the system POSTs I see it shows something about DRAC and it even gets an IP address. But I can't do anything (ping, web, telnet, etc) with that IP address.So basically what is the point of the basic DRAC without buying the full DRAC card? Just a placeholder?
View 7 Replies View RelatedIn 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.

Currently running ROMMON from S (Gold) region
Is this alright? Is the Gold region like a default region where ROMMON is always installed. And are F1 and F2 just storage partitions that are available to hold backup copies of the ROMMON? From what I read, it sounds like I can copy ROMMON images to F1 and F2, either the same version as the Gold region or different versions. Is that correct? Why would I want to copy different ROMMON versions to F1 and F2?
I have always done my port monitoring (SPAN) on Cisco layer 3 switches with no issues. This time I am trying to do this on a Cisco 2901 router:

I need to have the source port gig0/0 and destination port gig0/1. There is something about the gig port enumeration (slot/port#) that makes the command rejected. It is self explanatory:
#sh ip int brie
Interface IP-Address OK? Method Status Protocol
Embedded-Service-Engine0/0 unassigned YES NVRAM administratively down down
GigabitEthernet0/0 xxx.xxx.xxx.xxx YES NVRAM up up
GigabitEthernet0/1 unassigned YES NVRAM up up
Serial0/0/0:0 unassigned YES unset up up
[code]....
It doesn't matter what slot or port number I use, it is always rejected. The command is rejected for Both destination and source gig interfaces. I tried a wide variety of slot/port numbers. To my best understanding the complete port names are: GigabitEthernet0/0 and GigabitEthernet0/1, so why does it think there has to be another digit after 0/0 or 0/1? Does it have anything to do with the Embedded-Service-Engine0/0 being administratively down?
I can configure two APs as a bridge with one as an AP with RMW enabled, and the other in WGB mode. I have three VLAN, each configured on both APs with their own SSID. Each switch (cisco switches) port is in trucking with only the three vlan allowed. The APs are associating with each other but not passing VLAN traffic.
View 8 Replies View RelatedI have an old metal-walled mobile home that I plan on converting to a combination shop and man-cave; it's about 200 feet from my home's computer room, where I have a Netgear WNDR3400 wireless-n router. The only place in the trailer where I can "see" my home network is the kitchen window, and I thought about putting a Wi-Fi repeater there to extend the home network into the trailer. But I have read that using a repeater will cut the network's Wi-Fi throughput in half -- which would not please my wife and daughters back at the house. Is there a simple, relatively inexpensive way to extend the network to the trailer without slowing everything down? Eventually I may have Charter install a separate cable hookup there, which would allow a separate high-speed Internet connection too. For now, I just want to "share" Wi-Fi to the trailer.

Is it possible to create a wireless site to site link using 1260 access points as bridges (like the 1300 series)?
Also if so, can you use 11n channel bonding on the bridge link?
I need to link 2 buildings together wirelessly approximately 70 metres apart. There is direct line of sight between them.
Can the e1200 be bridges wirelessly? Or does it have to hardwired?
View 7 Replies View RelatedI have two Cisco 1300's acting as bridges only. I have created an infrastructure ssid on VLAN 2 and assigned this to the radio. I am carrying multiple VLANs between the bridges (using subinterfaces on the fastethernet and radio ports).I have enabled WPA-PSK, but how do I check that this is being used between the bridges? Also - I have a switch connected at each end of the bridge. When I make VTP changes, the remote switch does not pick these up - is this because VTP goes over VLAN1 regardless of the Native VLAN (2 in my case)? Do I have to carry VLAN1 over the bridge to get VTP working, or is there an alternative solution?

I bought this wireless router about a year+ ago, and it's just great. It's attached to the cable modem "downstairs" and right now it supports 2 smartphones wirelessly plus an ancient wired cable to an "upstairs" home office.

View 7 Replies View RelatedI have a point to point link of 9.27 km using 1410 bridges and AIR-ANT58G28SDA-N antennas as per the documentation that would be an easy to deploy link and it should work at 54 Mbps, eventhough it drops the link, it's so slow and the power measurments indicate -70 dbm (aprox) right under the antenna which is at 9 m height.
This is not the first time I have troubles with 1410 bridges, the other two times I had to change them for 1310 bridges. I wonder if it has to do with some configuration tunning like, external antena gain, link distance or anything else? By the wat this is ocurring in México don't know if that might be worth of taking into consideration in order to deploy a 1410 link.

View 2 Replies View RelatedI have a setup where - I have a cisco stack (4X SGE2010 Switches) trunking over to a 3COM switch. Both switches believe to be the "ROOT" of the network. Note The 3COM is running RSTP as opposed to the Cisco Stack which is running normal STP. To my understanding of STP - Essentially STP is not functioning! Both switches believe to be the "ROOT" so they don't shut ports down. (We are currently having major issues with ports going up and down for seconds at a time on both switches)

Can 2 N300 wireless bridges be connected to the same wireless access point ?
View 1 Replies View RelatedOkay so I have been using my E4200 router and WET610N bridges for a while now without any issues really until yesterday when I updated the firmware on the 4200 now none of my WET610N's (I have 2) can connect via wireless at all. At first I thought it was a a wireless issue but I have other devices that connect up just fine via wireless.I've made no changes to the router or the bridges before the firmware update.
If I hook the bridge directly to the router I can access it and configure it, but looking at the "Status" page, I see the bridge try and connect wirelessly but is quickly disconnected. Range isn't an issue as in my testing the bridge was 2 feet from the router.I've update the bridges to the latest firmware and have verified a 100 times that the settings on both my router and the bridges are set correctly (when the bridges are hooked up via network card).
