Cisco WAN :: 2921 Maximum Number Of L3 Ethernet Ports
May 2, 2011
How many routed ethernet ports do they support when using HWIC-1FE and HWIC-2FE modules? On the Cisco site for the two interface modules and in the corrseponding PDF of supported interfaces for 29xx routers a maximum number of 2 2port modules(HWIC-2FE) and 2 1port modules(HWIC-2FE) is written.Does this mean, that I can put in 4 L3 HWIC modules into one Cisco 2921 router by combining these two HWIC modules resulting in a total number of 7 interfaces for this router?

i would like to "team" two ethernet ports on a 2921 router into a single redundant link to a switch, similar to how an HP server teams multiple NICs to a single IP address. is port-channeling the best/only way to do this? i don't necessarily need the two links to be load balanced or bonded, considering the serial side of this router is just a single T1. i just want the links redundant, so in case something goes wrong with one cable or switchport, traffic will go over the other link.

I tried to add some more MACs to our Controllers through the WCS. I hate mac-filtering. We plan on stopping sometime. Three of the Controllers(4402s) are reporting that we have reached the max which appears to be 506.First, is there anyway to increase this number?Second, if not, any experience with deleting clients? Should I use reporting to find MACs that haven't been used for sometime and delete them? Is there a better way?

I know this sounds a simple and easy question, but I can't find the answer anywhere - so here it is :-I need to know the maximum number of vpn tunnels that a Cisco 881 can handle.(In context, we have a group of users, who work from home and this office, so their laptops have the cisco vpn client, I need to know how many of these vpn connections the 881 can handle at once before it dies a death.)Hote - I have read somewhere a line that state maximum number of users is 20 but think this was in reference to some VOIP service.

Is there a cisco best practice on the maximum number of NAT statements on a Cisco ASA? We have a 5520 and a coworker is adding static NAT policies so a vendor can monitor around 1,029 nodes. The problem is each node inside is a 10.X.X.X and to keep the IPs from overlapping with other customers the vendor monitors they would like us to NAT to a 172.16.X.X scheme.

We are having random issues of users not being able to connect to our wireless network consistently. The users will have successfully accessed the network previously but then will have difficulty associating to the network. After a period of time, the association appears successful again. My first thoughts were that there was a restriction on the number of clients that could associate to a given AP at any one time.This is the equipment we have:1x Cisco Wireless Control Server (WCS) 6.0.181.04x Cisco 5508 Wireless LAN Controllers 6.0.196.060x Aironet 1142N Lightweight Access Points (LAP) Is there a hard or recommended maximum number of clients per LAP? If so, where is this defined? From what I have read on these forums, Cisco apparently recommends about 25 clients per AP but I can not find any official documentation to support this.When I go to WCS Home > General > Top APs by Client Count, the top AP reports 20 clients. However, if I click on the AP Name and go to the Current Associated Clients tab, it is only listing 8 clients - why is this?

Is there a maximum number of licenses for connections to a 877?The reason I ask is that our routers are managed by a datacentre and when I asked for the login details I was told that I couldnt have them due to licensing reasons with no other explanation.

I have a few sites using the RV042 with wireless access points and some of them have over 50 devices.In reviewing the documentation (specifically,[URL]), I came across this:Enable DHCP server: Check the box to allow the router to dynamically assign IP addresses to up to 50 connected devices. Uncheck the box if you have another DHCP server on the network or you want to configure static IP addresses for your network devices.Is this accurate? Or will the RV042 allow more than 50 devices?

I need to know the maximum number of MAC addresses that can be entered in to the MAC security filter list on the AP541N.I know it has a maximum number of 200 concurrent users, however the documentation does not specifiy whether this also applies to the MAC filter.
I have used wireless acces points in the past that allow hundreds of users but only allow 64 MAC addresses, so this is very important.

I have a question regarding to the maximmum number of active SSID's on a WLC 5500 with 3500i, it's my understanding that the 3500i can support 16 active SSID's is it the same when connected to the WLC? Also, if possible would the WLC shutdown un-used Radios or maybe after hours?

I have a FWSM cluster that I exceeded the maximum number of static nat entries on. i migrated the connectivity off to a pair of PIX 535's that seem to be handling the adderess translation needs. however the number of NAT entries being required is increasing and being the PIX series wal EOL'd several years back..I need to replace them.. The static 1-1 nat entries cannot be summarized into network as the hosts that are being nat'd are scattered all over various micro subnets in the all 3 rfc1918 ipv4 address ranges and they are being manged directly by snmp and SNMP-trap and other services that prohibit the use of many-to-one nat. Is there a mknown maximum number of static 1-1 nat entries that can be defined on the ASA 5515-x, 5525=x and higher ASA firewalls? Say I wanted to be able to grow to 2500 or more static 1-1 nat entries. I am currently running 2010 1-1 static host nats currently.

What are the maximum number of AE2500 wireless adapters can be installed on a PC running Windows XP SP3 using the windows wireless zero configuration? Recently I'm working on a program that needs multiple seperate wireless connections on a Windows XP SP3 PC. Each wireless adaptor is given a static IP address to respond to traffic at some specific ports. I can install four AE2500 adaptors without problem, but it disconnects the first AE2500 device when I plug in the fifth AE2500 adapter. I've tried on different windows XP machines. They all get the same problem. I wonder if it is a limitation in the AE2500 driver.BTW I've also tried to install an Valet AM10 adaptor as the fifth adapter, it seems ok. Yet installing more AM10 adapters beyond the fifth (4 AE2500 + 1 AM10) requires some luck. It may disconnect the other AM10 devices when I plug in another AM10 adapter.

Background: currently have a WRT320N, thinking of upgrading to an EA4500 assuming ONE feature has been improved: Port Forwarding.
Scenario: Currently I have a WRT320N router, and while it "does everything we need" it has one limitation that is now getting in the way: limitation on number of forwardable ports. In the port forwarding panel, it has 15 total rows: the first five rows can be enabled for specificaly named services (SMTP, FTP, etc). The last 10 rows are fully customizable in that we can set the name, ports and protocol.
The problem is that of the 13 total ports I currently need to forward, only ONE of them is listed in that fixed list. So, sadly, I can only use one of those first five rows. I've now filled the remaining ten custom rows, and still have need for two additional ports (for now, may need more down the road).
Trying to get creative, I figured maybe I could just spill over to the Port Range Forwarding page and add a row or two there. The only problem: it's buggy. I've found that if the Single Port Forwarding list is filled, then the Port Forwarding Range entries don't work properly. For example, if I wanted ports 12345 and 12346 forwarded to 192.168.1.5, they work fine with two single port forwarding entries. However, if I delete those, add two other port lines I need forwarded (the single list being full again), and add a port forwarding range 12345..12346, they don't work properly, ports just are closed. Only the singles work, the ranges don't.
Question: Has the EA4500 resolved this issue and allow for either more lines (i.e. 20 customizable entries instead of 10), or, better, does it just have an [Add Entry] button to allow for additional rows to be created? In today's day and age, where one single device (such as an Xbox) can take four rows, a 10-row limit is pretty sparse. Comparing it to some competitors, for example the D-Link DIR-825 (aging, but still great) allows you to add as many as you want.
I realize "expensive" firewalls like SonicWall's have virtually unlimited customization, but I don't need many of the additional features and don't want to spend $350 on a "high-end" firewall to solve the problem of needing two more ports open.

We have an ASA 5505. 5505 comes with two default vlans 1&2 with each of them marked as inside & outside respectively.My query is , if i do not want to use vlans on 5505 and only want to use the Ethernet ports as pure physical layer 3 ports, is it possible?i.e. i want to assign a layer 3 ip address on eth0/0 and eth0/1 and make them as the inside & outside interfaces rather than vlans. is it possible to do away with vlans in 5505 & will it work otherwise?
