Cisco WAN :: How To Configure The 3925e
Jan 9, 2013
i looked but didn't find anything. I'm looking for a configuration guide, similar to the ASA Configuration Guide, that that can provide documentation on how to configure a Cisco 3925e router. I have my CCNA and a fair amount of real world experience configuring routers but ultimately what I am looking for is guidance on how to configure BGP on this beast. I learned a great deal about ASAs by running through the ASA Configuration Guide and I am hoping to do the same with the 3900 series ISRs.

I have an LMS 4.0.1 server (on Windows 2008 R2) with all the LMS and device updates applied that fails when trying to do an Inventory Collection on a Cisco 3925E router. The router is running IOS Version 15.1(1)T2. This device is apparently supported according to:

Some 'show ver' info:

I found a new bug in cisco IOS 15.1(4)M3 when running EEM script with syslog event detector.If system logging performed using the "logging discriminator" and run concurrently EEM script with syslog event detector, then Cisco router crash and goes to reboot.

I just installed a new ISR G2 3925e (spe200 integrated) in a VPN environment it works well but I lost latency (it adds around 8-10 ms in the VPN) because of " IPsec packet batching" :Queues multiple packets at the interrupt service routine level after being processed by crypto engine Reduces interrupt context switching by allowing one crypto interrupt for multiple crypto packetsIt's not very good specaly if you tunnel ToIP and/or video streamsI'm trying to find a solution how to disable it without impact other things or is there something planned soon to improve itfyi I use IOS c3900e-universalk9-mz.SPA.151-4.M.bin

How do I find the default throughput supported by the Router 3925E?I need a router that supports 400Mbps line 3900.The 3925E supports? If so, you need to upgrade or add a EHWIC? If so, what can I addto support that throughput?

I am definitely not a fan of ios 8.3, and specialy the change about "nat". I trying to use this example : [URL]
everything is good except : global (outside) 1 interface nat (inside) 0 access-list inside_nat0_outbound nat (inside) 1 172.16.1.0 255.255.255.0 Because, this example is for an 8.2 ios (or above), and i have a 8.3.
Another question : What the bestway to use this example, but with a single "nat" for all outbound traffic (I want all outgoing traffic (on the main FW) to be seen from a single domain encryption)

I have inserted a SIP-800 card into my CRS-8. I inserted the SPA into the SIP. I cannot find how I configure the SIP or the SPA. I have spent the day reading the manual but no where do I see the commands to activate or get the SIP up and running.

- the WAN consists of a in-house satellite network using comtech CDM-570 IP-Enabled Satellite Modems
- there is a group of HUB tx modems, each one is shared for approx remote 10 sites with a total bandwidth tx 2048k
- each remote site is to be guaranteed min 512k but can burst into the 2048
- remote sites must be somehow grouped to a member of each modem to set the bandwidth constraints
- a single DMVPN/multipoint GRE is configured on HUB. all remote sites connect to this (redundancy comes later )
The challenge is how to configure the QoS on the HUB side to meet this policy, Currently, I use ip nhrp group MODEM1 on each remote site, and ip nhrp map group MODEM1 service-policy output MODEM1 on the HUB. This is working ok. This works nicely, however I am left with the constraint that within each modem group I must define a class for each site and set the guaranteed bandwidth. As the policy is applied pre-encapsulation, I must create a class with an acl matching the remote sites IP ranges. An administration nightmare and prone to failure! I want to avoid this if possible.

I have Switch 6509E wich is the core of the network, and we have 4 llink form 4 ISPs, all the link will work at the same time?how can I confiugure the BGP , as I know if I configure bgp it will work with one ISP as an active link,if that link goes down it will automatically begin to work with other ISP. My question is that how can configure the network so that,some vlans work with one ISP, some vlans with the others and so on.If configure it with route map I will have to track every time to change the confiration if the links goes down, but I do not want to track it, Can I do anything with BGP to implement this task?The core of the network is Switch 6509E, intervlan routing is implemented on it, no dynamic routing is enabled.The firewall module installed on it the implementing the NAT processes.

I have a Cisco 1802 to connect my company to ADSL over ISDN. But my boss wants to change the ISP. The propose was (still is) to configure de router with VPN, IPS and use the WAN port to connect the new ISP, that provides an Ethernet signal to 100Mbps.The WAN port will work with Ethernet signal (when we change of ISP)?Any good book (or a paper) to configure the router to work properly with VPN and IPS?

I am relatively new to Cisco CLI and on the diagram that I am attaching I want the 2008 server to do DHCP for everything behind E0 on the Soho 91. I have tried multiple configs and I seem to get close but never quite get it. I am thinking that adding a DHCP helper on E0 will work but I am not sure.
This is my current show run:
clock timezone akst -9
clock summer-time akdt recurring
no aaa new-model

I'm baffled by a lot of new features of LMS4.2 and seem lost where to start looking.Our client needs to periodically make changes to switches to change their port settings.They have specific descriptions with a certain string. Let's say the description say "Cisco phone".The task is to create either template or ad-hoc Netconfig job that will send changes only to those switchports.

I want to create a VPN server on a linux Box for our company. I need to connect via VPN on private local company network and then i get the public ip address from here (company public ip address). This is because some of our system is only accessible from static company public ip, and the problem is the remote access (from home for example) to this systems.
How can i configure this VPN Server and what client can i use to connect and get the public ip address from the company and then connect to company systems?
