Cisco Switches :: Quoting SF302-08P For Client Having Offices Interconnected

Nov 8, 2011

i am looking at quoting the SF302-08P for a client which will have three small offices interconnected via single mode fiber. I am planning on connecting them to a 3560 switch. Each office will have no more than 3 - 7942 phones. I reviewed the notes on this switch and it seems it should support this phone type without any issues. Any support/reliability issues with this switch and the 7942s ?

Cisco VPN :: 3825 IOS EZVPN Client Timeout

Jul 10, 2011

I have a 3825 configured as an EZVPN server with 881 routers as clients.  One issue I am seeing is that sessions don't seem to time out, such as when a peer's public IP changes.  Show crypto ISAKMP peer shows the same host (using device certificates for authentication) with multiple public IPs establishing sessions.  I have ISAKMP keepalives configured on the router.

Cisco VPN :: Client Behind EzVPN Remote (ASA 5505)?

Feb 2, 2012

I try to configure a simple EzVPN infrastructure:
EzVPN Server (CISCO2811, hostname cme) < -- > EzVPN Remote (ASA5505, hostname ezvpn-asa) < -- > Client
Attached you find both configuration of the EzVPN server and remote. The tunnel is getting up and if I ping from the ASA to the Router, I see the packets getting encrypted:
ezvpn-asa# ping
ezvpn-asa# show crypto ipsec sa
interface: outside
Crypto map tag: _vpnc_cm, seq num: 10, local addr:

If I connect a client with IP address to the interface eth0/1 and do a ping to the cme, I don't see any packets getting encrypted. I don't have any idea about VPN, I just need it for a wireless lab environment. What do I have to configure on the ASA, so the inside traffic is encrypted?

Cisco Firewall :: ASA5510 - Routing From EzVPN Client To Non-LAN Zone

Feb 24, 2013

I got a Problem with Routing on a ASA5510.
I have ezVPN Clients connected to the ASA5510. Those Clients are assigned an IP from Pool.
I have a Router of a contractor connected to a dedicated ASA Interface called IBIZA with IP Net and the Router itself with the IP Behind that Router is another private Network which I need to reach from the ezVPN Clients.
The Connection from the ezVPN Clients to the "LAN" Interface/Network on the ASA works fine, but I cannot reach either the Contractor Router ( nor the Network behind that.
From the LAN Network (on the LAN Interface) I can reach both the Contractor Router and the Network behind.
When I use the Packet Tracer Tool from the ASDM it tells me that the Traffic goes through but ends on the LAN Interface. But it should end on the IBIZA Interface or am I wrong here ?
What do I need to tell the ASA to route the Traffic from the ezVPN Client to the Contractor Router and back ? I have set up the ezVPN Connection as full-tunnel so all Traffic goes through the VPN Tunnel. That shouldn´t be the Problem.

Cisco WAN :: 857 EZVPN - Cannot Ping Anything From Remote To Server

Mar 14, 2012

We have a VPN using 857 and 877 routers as remote connecting in to a 2800 EZVPN Server.

The VPN is working fine. However, the VPN connections sometimes (after a few hours/days) seem to "freeze". A "show crypt sess" shows the connections as Up/Active, but you can not ping antyhing from remote to server, or visa versa, nor does any traffic flow. I then added a "isakmp keep-alive" on the 2800, which improved the situation a bit, but not as much as I hoped.
On the 877 I then implemented a IP SLA, with Object Tracking and then use a Event Manager to just issue a "clear crypto session" . This solved the problem.
However, what do I do on the 857 ? It does not support Object Tracking or the Event Manager. Is there any other mechanism to monitor and reset these frozen/stale VPN connections automatically ?

Cisco VPN :: Does ASA5505 EzVPN Support Reactive Primary Vpn Server Feature

Nov 24, 2011

i am going to configure asa5505 as the azvpn client . and configre primay and secondary vpn server in the list.i find some feature that is support by ios ROUTER  ezvpn, not sure it will be support on ASA ezVPN???
will the ezvpn   fall back to the primary vpn server , if primary back on line,  on ASA? The Reactivate Primary Peer feature allows a default primary peer to be defined. The default primary peer (a server) is one that is considered better than other peers for reasons such as lower cost, shorter distance, or more bandwidth. With this feature configured, if Easy VPN fails over during Phase 1 SA negotiations from the primary peer to the next peer in its backup list, and if the primary peer is again available, the connections with the backup peer are torn down and the connection is again made with the primary peer.

Cisco WAN :: 2901 Terminal Server And Restricting Access

Apr 19, 2011

I have a Cisco 2901 Terminal server with AAA authentication via ACS server.  I create twoaccounts on the acs server, cciesec2011 and vendor.  Both accounts can log into the Cisco 2901 Terminal Server without any issues.  By the way, I am NOT using AAA authorization on the  Cisco Terminal Server.  Once cciesec2011 or vendor accounts are authenticated, theseaccounts can access all the async line on the Cisco Terminal Server.
Now I have a new requirements.  I would like to allow cciesec2011, once this account is successfully authenticated, this account has access to ALL async line on the Terminal Server.  The "vendor" account, I want to restrict this account access only to async line 35 (there are 32 async lines available on the Cisco Terminal Server) and nothing else.
How can I accomplish without using AAA authorization on the Cisco Terminal Server?Is it possible to use "privlege level" to accomplish this?  if so, how?

Cisco :: Router 2901 As NTP Server For Windows 2003 Network

Sep 19, 2012

I am trying to configure a 2901 router to act as NTP server on my network.This set "ntp master" in the router.I have no possibility to access an NTP server on the Internet.Now I want to configure a Windows 2003 DC to update the time from the NTP Server (router 2901).In Windows 2003, the registry value "Ntp Server" may have to be IP addresses or FQDN? (In my case I put router_ip_address, 0x1) 0x1 = use this "SpecialPollInterval" to update the time? Where you can find that these actions mean "next action is 3"? In Event Log in Windows 2003 DC receipt Event ID 35:The time service is now synchronizing the system time with the time source ROUTER2901_IP (ntp.m | 0x1 | W2K3_SERVER_IP: 123 -> ROUTER2901_IP: 123).Configure "Special Poll Interval" in 10 seconds.But the time on the Windows Server 2003 DC continuous five minutes ahead of time compared to the 2901 router.

Cisco VPN :: 5505 Create VPN Tunnel Between Two Offices

May 27, 2011

I have two cisco ASA 5505 devices and two cisco switches plugged to ASAs in each office. I need to create a VPN tunnel between two offices.
-Network behind the ASA1 in office1 is with DHCP server –
-Networks behind the ASA2 in office2 are; and
 All computers in office2 need to get IPs from DHCP server I have switch in office2 with 3 VLANS and I can assign computers from different subnets to different VLANs.How can I archive this goal? Should I assign 3 IPs for ASA2 inside interface (, ...5.129, ...5.193) as a default gateways for each subnet? Should I put dhcp helper address on the switch for each VLAN?

FVS338 / FVS318 / VPN Between Offices For VoIP?

Jan 19, 2012

I have an Avaya IP office setup on a 1.5 mb T1 PRI at location 1. My second location is going to run IP phones over 15mb/1mb DSL connection. All calls will generate from the IP office at location 1. I will have 6-8 IP phones at location 2.I assume i need a VPN setup between the two office for the IP phones to work. I've been looking for the best VPN solution and it appears for a budget the Netgear FVS318 or FVS338 is the way to go. If I go that route do I just need a FVS338 or FVS318 at both locations?

Best Connection Options To Share Files Across 2 Offices?

Feb 18, 2011

Have 2 office locales. Currently have a Site to Site VPN over the public domain with 1 T-1 line on each side (different carriers). The performance is _poor_. A 2MB Excel file takes over 1 minute to open at the remote location (takes less than 10 seconds at primary location).Have approximately 20 users at the remote location (about 200 miles away); entry level firewalls; and primarily only work with MS Office files.

1) What are the differences between "Private Ethernet", "MPLS VPN", "Point to Point T-1s", and just old fashion Site to Site VPN? and is there one in particular we should focus on given we only have 2 offices?

2) Do we simply just need to increase our pipes on both sides from T-1s to 2 T-1s or a 10/10 IDE line to make our S2S VPN acceptable?

3) Is all that's really needed for P2P T-1s is to have the same carrier at both locations (this is available)? Do we still need VPN or if it's all over the same carrier it is secure?

4) If we go with Private Ethernet or Point to Point T-1s, would we then need another pipe to just get to the internet?
