Hi, For my home LAB, as i am studying for CCNP, I looking to use this old ISDN 1812 to serve as a terminal server. I just cannot get it to work. So before I bother you with other questions, could it be done with an Cisco1812? The tutorial I'm using is: https://networklessons.com/cisco/ccie-routing-switching/cisco-terminal-server-configuration-example They are using an Cisco 2511-RJ, but without explaining why.. I just can't find if my Cisco 1812 is suitable for this purpose. The only difference I see thus far is that the tutorial lists TTY lines and my 1812 VTY lines.. Google tells me that they are almost the same. Is the difference why this is not working? Can someone help me with this? Thanks in advance! Greeting Marnix The full specs: Cisco 1812 (MPC8500) processor (revision 0x400) with 236544K/25600K bytes of memory. Processor board ID FCZ1526917R, with hardware revision 0000 10 FastEthernet interfaces 1 ISDN Basic Rate interface 62720K bytes of ATA CompactFlash (Read/Write)

Thank you all for replying. The 'show IP DHCP binding' showed the leased IP. It's indeed possible thet te Internet was looking for the adresses in te /29 range of subnet. Some appliences use these IP's So I think the case is closed! Thanks all!

Hi all, On a Cisco 887 DHCP handsout adresses. At this moment only one device is connected to the Cisco, but it still handsout multiple IP with no mac. Is this normal? Router#sh arp vrf INTERNET Protocol Address Age (min) Hardware Addr Type Interface Internet x.x.59.177 - xxxx.ae44.ffdc ARPA Vlan1 Internet x.x.59.178 0 Incomplete ARPA Internet x.x.59.179 0 xxxx.1699.dc5f ARPA Vlan1 Internet x.x.59.180 0 Incomplete ARPA Internet x.x.59.182 0 Incomplete ARPA ip dhcp excluded-address x.x.59.177 ip dhcp excluded-address x.x.59.233 ip dhcp excluded-address vrf INTERNET x.x.59.177 ! ip dhcp pool INTERNET vrf INTERNET network x.x.59.176 255.255.255.248 default-router x.x.59.177 dns-server 8.8.8.8 4.4.4.4 Can anyone tell me why this happens? Is this a standard procedure or did i do something wrong? Thanks in advance

Thank you all for replying. It's on one of our ASR1004's. And the client is logged in on two separate locations, causing this error. He doesn't know which, so Im deleting the whole profile. And see what happens. Chreers anyways! Mx.

Hello, Can anyone help me with shutting down an virtual interface, Vi2.1062? Somehow the PPPoE session created two interfaces and I can't see how or correct the error. I also cant post the runnin-config, we've got over 40.000 customers, so it's simply to large. Where do I go to correct an error likes this, or where do I start looking? Any help would be appriciated!!

Thanks for the reactions. I corrected te x.x.x.135 error in my post. I will try to post the config soon. I need to take out all the client information and keep it logical. We are using an Cisco 897 which is a router/modem for average companies. It has a switch module integrated. I believe it uses the routers 4 LAN ports for routing. But correct me if I'm wrong.

Hi, as a starting network engineer I am puzzled by a problem on of our clients has.. we cannot ping certain IPs within the network and others we can ping. This happens on a Cisco C897VAB-K9. I’ve checked the ARP table and all IP register. But when I ping x.x.x.141 on vlan101 with source vlan 104 nothing happens, but when I ping x.x.x.135 on the same vlan from the same vlan104 the ping is successful. I also cannot ping any of the default gateways for those VLANs, which is strange because the x.x.x.135 is on VLAN 101. So what am I missing here? The C897 router has Ethernet ports and vlans configured. It should in my opinion work.. some config: interface Vlan101 ip address x.x.x.190 255.255.255.192 no ip redirects no ip unreachables no ip proxy-arp ip nat inside ip virtual-reassembly in ip verify unicast reverse-path ip tcp adjust-mss 1452 no autostate interface Vlan104 ip address x.x.x.126 255.255.255.192 no ip redirects no ip unreachables no ip proxy-arp ip nat inside no ip virtual-reassembly in ip verify unicast reverse-path ip tcp adjust-mss 1452 no autostate

Hi, As a recent CCNA R&S graduate I'm still a bit confused when it gets to extended ACL's combined with static NAT. So I got this question; If you create an extended ACL and you use this command: permit ip 10.0.0.1 0.0.0.0 any All protocols are permitted with their associated ports, right? And if you then use a static NAT command such as: ip nat source static tcp 10.0.01 3389 interface Dialer0 3389 There shouldn't be a problem.. connecting to 10.0.0.1 through the IP of Dialer0.. Or do I have to include the protocol and port-number in the ACL? Greeting Marnix
