I have ordered 1 GB internet service (BW) hand off from Bell. The firewall will be the gateway for 5 offices with total 200 users. I would like to install CISCO ASA 5500 series as internet gateway. ASA will have VPN to AZZURE as well for AD and SQL sync. Can you suggest the ASA model best fit for us? Current firewall is 5508 X which handles 1 office (40 users) and 200 GB hand off but we are upgrading the circuit to 1 GB and adding 4 more offices (total of 200 users).

I'm experiencing a Linux routing problem.

Environment is SLES 12 SP2, running on some HP server machine with 8 physical, used network interfaces, running in a non-internet local network.

Most physical network interfaces (eth0 ... eth3 and eth5 ... eth7) have (local unique) static IP addresses in non-overlapping networks, and the routing table looks ok. The interface eth4 is on DHCP.

The problem is that sometimes packets seem to be sent over the wrong interface - a packet that is expected to fly thru eth6 is spit out on eth0. This happens erratic and causes to application software (managing measurement data) to loose the data stream after max ~15 minutes .

As fa s I can see,

the exit interface of the wrong-routed packets is always eth0

there are packets of at least 2 interfaces routed wrong

the configuration of eth0 (viewed by YaST and by inspection of /etc/sysconfig/network/ifcfg-eth0) shows no IP addresses from the other interfaces networks

If I take down eth0, the application runs smooth (but that's only acceptable for testing matters).

If I record the network traffic of the network addresses for eth2 (tcpdump), I find i.e. suspicious ARP requests originating from address on eth6 with an originating MAC address of eth0.

Any idea what happens here ?
Any idea how to fix it ?

P.S.: Due to some policies demands, I can't do any driver etc. updates on the system. Same appies to ideas like "do DHCP on all interfaces" ... I can't change that.

Aruba Wireless 802.1x losing username.

So we have a bunch of Aruba 215 access points running with a virtual controller.

I have set up a radius server and from the CLI i can successfully authenticate

aaa test-server ISE-01 username aaron.street@park-now.com password <password> auth-type pap
Radius server ISE-01 test successfully

on the Radius "ISE" server i see

Event	5200 Authentication succeeded
Username	aaron.street@park-now.com
Endpoint Id	A8:BD:27:CF:3B:8E 
Endpoint Profile	HP-Device
Authentication Policy	Default >> Default
Authorization Policy	Default >> Basic_Authenticated_Access

Open in new window

However when i assign these radius server to a SSID and try to authenticate a client it gets

Event	5400 Authentication failed
Username	USERNAME
Endpoint Id	A4:50:46:1F:13:33 
Endpoint Profile	
Authentication Policy	Wireless_POC >> Default
Authorization Policy	Wireless_POC

Open in new window

where did the USername go? This same set up on ISE works fine with the Meraki wireless but Aruba is having issues.

HAs any one else has issues trying to run PEAP and EAP-TLS on Aruba wireless over 802.1x

Hello Experts,

Anyone can recommend a good cost effective Intel 10 gig card to be used with HyperV on Windows 2016?

I used them on 2012 R2 and they are perfect, but not sure if they are good on 2016

Hi,

We have an APC Back-UPS Pro 1500 and an 8-Port 10/100Mbps Desktop Switch (TL-SF1008D).

We wish to plug our switch into the UPS in case of power outage.

The UPS requires a kettle plug be plugged into it.

We only have a power plug that would go into wall socket for this switch so it won't plug into the UPS.

How would you recommend we plug our switch into our UPS?

Thanks,
Robbie

2x 24-port patch panels or 1x 48 port?

Hello
It is better to have two 24-port patch panels or one 48-port panel?. We are making a single IDF closet for 4 floor building and all UTP cables will run to single closet. As per cabling contractor, the cables are under 90m length.
IDF is currently designed to have 12x24 patch panels and 7 access switches.
Also is it good idea to have single IDF closet ?

Any thoughts ?

I'm looking for some help re-configuring my home network. Here is current setup:

Comcast cable comes into data enclosure in garage wall to a 2-way Splitter. One coax goes to Gateway in my office. Patch cable out of Gateway to a switch beside it which connects my desktop and network printer. Patch cable from this switch to the wall jack backfeeds back to the data enclosure in the garage. Patch panels in the data enclosure connect to small switch in the data enclosure to provide network to other jacks in house.

First, I'm planning to ditch the Comcast Gateway and go with my own modem and router. I want to add a Ubiquiti Cloud Key Gen 2 Plus and eventually a couple of security cameras as well. I'd like to centralize things a bit more instead of going to my office and then backfeed to the data enclosure before distributing to the rest of the house. Unfortunately, there isn't room in the data enclosure for the router, modem, etc. and even if there was, I'd be concerned about the temps. It can get pretty hot in the garage (90F+).

The room directly above the data enclosure in the garage is a storage room with heat and A/C. Perfect location for the network equipment. And it has a knee wall I can get behind and access the cables going down into the garage. But I'm not sure how best to proceed.

There are 17 Cat5e cables coming into that data enclosure in the garage, 7 from top (upstairs jacks) and 10 from bottom (downstairs jacks). There appears to be enough length on the …

We have a Cisco 6509E chassis as the core of our network. We are trying to run our FOG (Imaging software) server and we are finding multicast is not working through the switch. We tested this by plugging the server into a variety of other switches that bypass the core and multicasting works perfectly. I am unsure what settings could be different as I have compared IGMP Snooping and the portfast settings with the switches that work when the server is plugged into them.

Any ideas? It is running SUPT2XL as the supervisors running 15.1 on them.

How to rack Cisco 93180 Nexus in a rack with doors

I just arrived on site at a colo where a vendor installed a patch panel and 6 Cisco switches. The cabinet door won't close because the switches and the patch panel are mounted flush with the front rack posts, so the cables (especially, the fiber connectors) extend out from the switch preventing the door from closing. So I've called the vendor and they are going to help but not now.

These are Cisco 93180 switches, with port side intake. How should these switches be installed in a rack with doors that close flush with the front posts? On a shelf? Is there a way to recess the switch?

A small conferencing center needs help boosting their AT&T cell phone signal.
They are in a wooded area, and it's an old building, with metal mesh in the exterior walls, and several fireplaces with stone walls. There's a big kitchen at one end.
The building is long, maybe 200 feet from end to end.

Can a building have more than one booster?
Which one should I get?

I saw a pretty persuasive web page from Wilson Amplifiers, that placed high on a DuckDuckGo search.

Hello, I am working on a Linksys EA6300 router when I connect to it using the 5G wifi connection the highest speed I can get is 25mb and the 2.4Ghz around 10mb but if I use the Xfinity Model: TG1682G router wifi connection 5Ghz I get around 250Mps down and the 2.4Ghz is getting about 20mb down. The customer has been using two router on separate networks just to extend the coverage but this is becoming a problem due to the speed of the Linksys ea6300. My question the Linksys has 10/100/1000 connections so I was thinking the connections should be a bit faster than this? Any suggestions? I know this is a poor man's way to have it set up but it has been working for them over the past few years
