Cisco WAN :: Using Cat6500 For A Small Hosting Company
Jan 9, 2012
I am running a smaller hosting company and i am currently looking at a Cat6506 switch with a SUP720 Supervisor Engine. I have also been looking at a Cat6509 with a SUP2-GE Supervisor Engine. At the moment i am getting my connection from a ISP but i am going to get my own BGP AS now.. My question is just, how much will the SUP720 be able to route, and how many routes will i need to get it to route my packets in and out of my AS? I have seen that the full BGP table is over 400,000 and the SUP720 is only capable of 256,000, but do i really need the full table? I
major differences between the SUP720 and SUP2-GE Supervisor Engines?

I would like to know the basic configurations for Win Server 2008 Standard for a small office (60 clients) The company has a Sales, HR, warehouse, and Accounting, and VPN for some sales, what configuration do you recommend me for each area? Right now my server has DHCP, DNS, and AD (do I need to install any other role?), Also what other configuration do I need in order to control my clients and users, and for security? how can I make the clients to save their files in my server? or make a copy of their files from their computers to my server? Any information for security? in my server or Router?
Like the tittle say, I just want to know all the configurations needed in a network for a small company.

Is it possible for Windows 7 to host multiple domains? I have seen that it is available for plenty of other OSs and I am sure that it is. I just wanted to make sure.

I am playing Hidden Stroke online and i can join games but i cant host, when i create a game my IPV4 address shows up instead of my IP address which means no one can see the game. I am a guest PC on my home Wifi.PS i have already opened all the ports that the game requires to play.

On Windows XP, my integrated NIC stops working after hosting a server. The server starts fine, ports are forwarded, firewall is down, modem is fine, but when I receive a connection, it shows they have made a connection, but then they drop, as do I. I can't browse or ping anywhere. I have to physically disconnect, then reconnect the ethernet cable to the port, or restart the computer. Upon ipconfig, the adapter is set with the Windows default ip (169.x.x.x) and cannot be /release'd or /renew'd.

So 3 days from now im getting comcast cable....12 mbps download and 3mbps upload (something like that)I want to know if I can host servers in online games such as... modern warfare 2 and black ops...pretty much any popular first person shooter. I noticed that every game I play I am not host and I am lagging...my current connection is 2.5 MBPS download and 0.4 MBPS upload.

I recently signed up with AT&T U-Verse. They required that I buy a 2Wire 3600 HGV router. I looked up how to forward ports -- and even called an AT&T representative -- and I am sure that I forwarded them correctly. I'm trying to host a Minecraft Server. I forwarded port 25565 in TCP and in UDP. After that wouldn't work, the AT&T representative said that the traffic was being blocked from my side. I then checked my Windows Firewall and allowed all proper applications -- Minecraft and Minecraft Server. When that wouldn't work, I went in an manually added exceptions to Windows Firewall for TCP - 25565 and UDP - 25565 Inbound and the same for Outbound. Nothing.I have tried to check the ports in DMZ mode with Windows Firewall disabled -- they are still timing out. What should I do?

We're trying to set up netflow based billing for our hosting environment. We're dual homed to two different ISPs using BGP peering with each (ASN 18817). The drawing below shows the logical setup: The routers are each Cat6506E with Sup32 and PFC3B/MFSC2A running 12.2(33)SXJ. The direct link between is layer 3 (routed ports) for iBGP peering. The dark line is a layer 2 LAN made up of multiple switches (not shown) each connected to both 6500's with spanning-tree for loop protection. These switches also provide a layer-2 path between routers but the configured BGP peering is set to the layer-3 port IP on the link. There is at least one firewall connected directly to a 6500. The firewalls are all ASAs connected to any one of the not-shown mid-span switches. The router interfaces to the layer-2 LAN is a VLAN SVI using GLBP to provde a redundant gateway. There are multiple subnets on this vlan configured as secondary IP addresses on the VLAN interface (and in the GLBP gateway configs).
The question is: how do we collect stats from all traffic to/from the internet without collecting any local traffic (firewall to firewall) and without getting duplicate flows sent to our collector?
I was hoping to just put "ip flow ingress" and "ip flow egress" on the ISP facing L3 ports but that's not actually collecting outgoing flows (appears egress netflow may not be supported on the 6500). I added "ip flow ingress" to the VLAN interface but that didn't seem to fix it so I also addes the global command "ip flow ingress layer2-switched vlan 50". However after a small change to the layer2 LAN some (but not all) of our clients saw a near doubling of bandwidth (according to netflow). We compared the netflow stats to the server port usage stats for one client and it looks like we were under reporting before the change and appear to be over-reporting now. I'm thinking the overage is either because we're counting MLS traffic flowing between subnets on the layer-2 LAN but can't verify. With GLBP moving the default gateway and MSTP blocking at least one uplink from a mid-span switch to a 6500, traffic flows can be difficult to predict. Especially when you don't know exactly when a flow gets accounted. For instance, if a packet comes into one 6500 becase that's the only layer-2 path to the gateway BUT the gateway is currently on the other 6500, does the first 6500 count that flow or does the second one count it or will both? etc etc.

I am setting up a webserver to host our website on our local network. When I'm browsing from an external network, I can pull our website example.com and a sub domain test.example.com. However, when I'm browsing from our internal network, I cannot pull up test.example.com. I am not sure if this is due to propigation issues or what.When I do nslookup from external, it shows my network's main IP address. When I do it from local, it can't find an address and says non-existent domain.Should I have any problems connecting to my website if it is using my external IP address? Will this be a loopback problem? If so, how can I resolve this?

I had setup 2 servers at home. I'm now in need of hosting 4 websites. I have 4 static public ip's. I'm currently using a router with DD-WRT firmware installed. I have setup up as static NAT. X.X.X.27 to 192.168.0.100, X.X.X.28 to 192.168.0.101. This is my current setup for the existing 2 webservers which host a website each. I notice apache allows for multiple websites per server. One of the server's is a dell 2500 with 2 NIC's and will not be a problem assigning two ip's. The second server only has 1 NIC. Should I buy another NIC card for the second server or could I get by using a virtual NIC? The load on the servers isnt heavy. Only bout 20 clients connect to them daily.

I would like to setup multiple DMZs for our hosting servers. Currently there is a single DMZ in which our reverse proxy servers are connected using a public IP address. The idea is to have the reverse proxy forward the request from the Internet to the hosting servers in another DMZ. The purpose of the hosting DMZ is to protect it from the outside as well as from the inside. There will also be a development DMZ where we can test content prior to going live with the website.
Network: We currently have two Cisco 6509's (Core) with a FWSM in each running active/stanby configuration. There is a 10Gb Fiber connection between each Cisco switch to two Cisco 4948s (Top of Rack Switches). I can either setup OSPF or Trunking between the core and top of rack switches. The Cisco 4948s will support VLAN 7 (hosting DMZ 10.0.7.0/24) and VLAN 8 (development DMZ 10.0.8.0/24). Each webserver is connected to both Cisco 4948 for redundancy.
Question: If I have a single interface connecting both VLANs 7 and 8, either through Layer 2 or 3, then how can pass both DMZ traffic to the appropriate servers? The reason why the servers are in the same rack connected to the same two switches is that we are using Blade Servers and VMWare.

I ran into interesting issue on Sup-2T. As you probably know, QoS CLI is changed on this new supervisor. I'm looking to translate incoming dscp-marked packets, into exp-marked on egress.Now, according to documentation - Catalyst 6500 Release 15.0SY Software Configuration Guide - this functionality is still called mutation-map and is configured under 'platform qos map exp-mutation'. The problem is quite simple – there is no 'platform qos map exp-mutation' on 2 different machines I checked upon. Here:
Some-6513(config)#platform qos ? 10g-only qos pure 10G mode aggregate-policer Named aggregate policer marking marking keyword
police police keyword protocol protocol keyword queueing-only queueing-only (no QoS rewrite, no policing) rewrite packet qos rewrite enable/disable statistics-export qos statistics data export

I need to use IP SLA to monitor remote routes on CAT6500
CAT6500 is running "sup-bootflash:s72033-jk9o3sv-mz.122-18.SXD7b.bin" on SUP720
Feature Navigator said it is
ENT FW W/MPLS/IPV6/SSH/3DES After drill down into feature set I found that this version support for IP SLA such IP SLAs - ICMP Path Echo Operation
BUT, back to console I can not do such (config) ip sla command (not found cmd CAT6500(config)# ip sla 1) What I did wrong or others cmd imply this ip sla process?

I have to do a policy route on my cat6500. basically, I want to redirect all traffic from 10.1.1.100 to internet address xxx.xxx.xxx.xxx to another machine 10.1.1.101. however, the 10.1.1.100 and 10.1.1.101 are in save subnet. not directed to cat6500, but both connecte to same switch which is linked to cat6500. However the 10.1.1.101 is not a cisco router. but some sort of equipment which change traffic and pass them to another subnet.
that means can I do below:
access-list 101 permit ip host 10.1.1.100 host xxx.xxx.xxx.xxx
route-map reroute permit 10
march ip address 101

I have a ASA 5505 that I have been using to test run the IPSec VPN connection after studying the different configs and running through the ASDM I keep getting the same issue that I can't receive any traffic.
The company LAN is on a 10.8.0.0 255.255.0.0 network, I have placed the VPN clients in 192.168.10.0 255.255.255.0 network, the 192 clients can't talk to the 10.8 network.
On the Cisco VPN client I can see lots of sent packets but none received.
I think it could be to do with the NAT but from the examples I have seen I believe it should work.
I have attached the complete running-config, as I could well have missed something.
FWBKH(config)# show running-config

I want to use the ACE blade in CAT6500 to loadbalancing SYSLOG events towards (SIEM) collectors. Servers and network devices will sent there syslog messages to different collectors after being loadbalanced by ACE. I was just wondering, since a lot of clients are going to sent there complete syslog events to the VIP and thus introducing a high connection rate. (+/- 200.000 CPS) According to the specs, the ACE blade has a limitation of 325.000 connection per second. I suppose this is a limitation at device level. (not on a per context basis, and does that include both TCP and UDP packets?) Could the UDP BOOST feature might come in handy allowing very high rate UDP syslog packet loadbalancing?

how to clear vty line? Please see below. A sh tcp <line number> shows that the TCB is waiting for TCP Process. The TCP processs TCB is waiting for is SSH. I believe because of this ssh process still running, the vty line cannot be cleared.

I am trying to figure out if the new code for ASA SM 9.0(x) or 9.1 is compatible with CAT6500 but I could not find any document that explicity confirms the the INCOMPATIBILITY. This table from the Release notes is not quite clear.
[URL]
It says that code 8.5 is compatible with Cat6500 and version 9.X is compatible with R7600.So are the two different trains now, one for Cat6500 and one for R7600?
My real goal is to find the correct software versions (not interim) that provides compatilibity with Catalyst 6500 with Supervisor 2T and ASASM.

Using the new SUP-2T, need to clarify one query. If we are using the new SUP-2T in VSS mode, will the new ASA service module and NAM-3 are supported? From Cisco site, ASA module FAQ:
Q. Will the ASA Services Module support the Cisco Catalyst Virtual Switching System (VSS) at FCS?
A. Yes, depending on which supervisor you use. The ASA Services Module supports VSS either as a single firewall or as a failover pair of firewalls, when used with the Supervisor 720-10G (VS-S720-10G-3C and VS-S720-10G-3CXL). Transparent and multi- context modes also work with the VSS in this configuration. However, though the SUP 720-3B (WS-SUP720-3B and WS-SUP720-3BXL) is supported by the ASA Services Module, it is not capable of supporting the VSS. No reference to Supervisor-2T.

We have IP device on the farm switch(cat6500, which is an access layer siwtch), with the gateway on the core switches (Nexus7000), on the core when I do show ip arp, I found the mac.But when I do sh mac add add of that mac there is no port attached to that mac.
Since that particular vlan only resides on the cat 6500 and two cores, so I logged in to the 6500, and when I show mac- in that vlan, I didn’t find that mac addresss. Instead, I found another mac address with last 8bit are the same of that mac.
Is it some kind VIP of the mac? How so, if no port, how can the switch forward the frame? [code]

By default SBS 2011 places a shortcut on the desktop to companyweb and adds shortcut in the start menu under Windows SBS to companyweb as well.
I found the instructions to edit out the xlm file for SBS 2008 to prevent this from happening but that does not work with SBS 2011 as I do not see those settings.
I did also find the login script for SBS 2008 settings to remove those after the fact all of the time and that is easy enough to change to make it work with SBS 2011; but I would much rather just prevent the shortcuts from being placed in the first place.

Nowadays my Company works with autonomous APs (AP1142 most of them.We have a WLC 5008 and I am working on the implementation project... So far so good.BUT, I have just realized that the Company didnt buy a second WLC (this project started 1 year ago and I wasnt an employee here yet...).If I transform all autonomous APs we have (around 25, locally and some of them remotes)... And then If I have a HW problem with our single WLC... those APs will continue working ?
