I just managed to get my hands on a CISCO 871 router but when I turn it on I have some errors:
*** Data Access Exception ***
PC = 0xfff3026c, Vector = 0x300, SP = 0x8000498c
The first time I powered on the router it booted, then I turn it off and since then I have this errors every time it boots up. If someone can give some info about the errors so I can try to remediate.

View 1 Replies View RelatedI have a problem to solve in our data center, see attached drawing. HW: Our core switches consists of two stacked C3750 with ip routing. What I want to do is probably simple but I haven't been able to figure out the best method.
VLAN10 and VLAN20 should not be able to communicate with each other. (ACLs?)VLAN10 will have it's own default route/firewall. Both VLAN10 and VLAN20 should be able to send server backups to server in VLAN30. All 3 V LANs come in on a trunk from a pair of stacked C2960-S. I need it to be able to scale if we have 50 VLANs for instance, hopefully without long complicated ACLs. I've been considering VRF's, PBR but can't decide what's the simplest solution to this problem. I have never done this before so I would prefer to start off on the right foot.
For the past few days I've been attempting to configure a data T1 on a Cisco 1760, but I'm stuck at:
Serial0/0 <our ip address> YES NVRAM up down
To provide a bit of background. This router used to be configured with a T1 via Frame-Relay; which worked fine. Now we recently change offices and providers, and the provider did not offer any information as to which encapsulation type to use, and if Frame-Relay which DLCI to use, etc.
Now I've been trying to setup the T1 connection and testing various settings such as encapsulation HDLC and PPP, but no luck. I also played around with the line codes and framing; which resulted in the following framing sf int down, line prot down, framing esf int up, line prot down. Regardless no luck.
Now I've been following several guides and examples mainly the following: [URL] In this guide they make mention of a WIC-1DSU-T1-V2, but as you can see in the show diag snippet at the bottom; we have a WIC-1DSU-T1 version 1.5. I dont' know if this poses a problem for us.
Throughout the entire process I've seen a few irregularities for example:
1. Router(config-if)#service-module t1 cablelength short 110ft
^
% Invalid input detected at '^' marker.
The IOS doesn't recognize any command with service module t1 ca , and the only recognized command with C is clock.
2. If I enter the following list of commands under the serial interface:
!
interface Serial0/0
ip address 10.0.0.51 255.0.0.0
service-module t1 framing esf
service-module t1 linecode b8zs
service-module t1 timeslots 1-12 speed 64
[code]...
And I do a sh run all I get is the following:
!
interface Serial0/0
ip address 10.0.0.51 255.0.0.0
load-interval 30
!
Although i can do a show service-module s0/0 I can see all of the configured parameters (see below)

I am trying to connect a cisco catalyst 3750g-48ts with our exsiting 3com corebuilder 9000 using the SFP ports, I have established a link and the interface is up.
The issue is that no data is passing through between the two, everything looks like it's up and enabled, spanning tree has detected the uplink port and has automatically set it to forward, both devices suggest the link is in place and the lights are on .
I am really new to Cisco and having a hard time with my Cisco 2800 series.
I have two sites connected with each other Site A and Site B (Using the same Cisco 2800). Now site A can connect to site B on the Cisco and the internal network, but site B can only see the Cisco and not the internal network of site A. So all the traffic is coming in to site B but can't break out of site B. I have tried everything I can think of but again my knowledge of Cisco is not good at all.
We recently purchased two 3750-X 48-port switches. We are in the process of connecting the Data Stack and StackPower cables. The question we have is what is the recommended Data Stack and Power Stack cable configuration if you only have two switches? All of the documentation that we have seen is for three or more switches.
Data Stack: Our assumption is that we will go from Stack 1 on the top switch to Stack 2 on the bottom switch. Do we need to then connect another cable from Stack 2 on the top switch to Stack 1 on the bottom switch? We would think not, but figure we should check. We plan on adding another three in the next budget year, which starts in May.
StackPower: Our assumption is that we will go from S-PWR on the top switch to S-PWR XPS on the bottom switch. Do we need to then connect another cable from S-PWR XPS on the top switch to S-PWR on the bottom switch? We would think not, but figure we should check.
We are currently experiencing random multicast data dropouts on ports that are connected to a 3750X in VLAN ports. A test PC was connected to a routed port and we do not have any dropouts of the multicast data.We also took a 2960G and plugged it into VLAN ports on the 3750X. Any test PC that is on the 2960G does not lose traffic. The traffic only drops on PCs that are connected to a port on the 3750X that is in a VLAN. The data drops are random and last approximatly 55-59 seconds before we start receiving multicast traffic again.
I do not see any input/output errors on the interfacessh platform port-asic stat drop also show no drops
CPU runs at about 50% on the 3750X
Below is the configuration of the 3750X

View 3 Replies View RelatedI am trying to connect a Control network that can not have access to the Internet, or any other network for that matter, to my Admin network so that I can retrieve trend data about the plant that goes into a database. Right now the process is print information, hand jam into excel spreadsheet, print again, and hand jam into another excel spreadsheet on the other network. Reports are printed automatically once a day, but would like a simplified way of getting data from one network to the other without having to re-enter data several times. Current policies stipulate no USB drives connected to Control systems. Even if we could loosen that, personnel needed to transfer data is not available and going to each individual machine would take more time than current system.Now that background is laid, I have two 2911 ISR routers with EIGRP configured, each with a 4 port EHWIC card. The 3 L3 ports on the router are setup as follows: interface G0/1 to the internet, interface G0/2 to a wireless back haul, and interface G0/0 for IT network. I then have 3 VLANs setup on the EHWICs for our Admin network. We will move the IT network to a VLAN on the remaining EHWIC port and connect the two 2911's through the G0/0 interface. I am going to have one computer on my Administration network dedicated to receiving the information and have a program that will take that data and import it to a database. I need to allow only that computer to receive traffic from the Control network and I need no traffic to flow back into the Control network. In other words I will transmit data from the control network to the admin computer using one protocol (TFTP more than likely) and block any other traffic coming out of and going into the Control network.
View 1 Replies View RelatedI have a Cisco 6500 which has two VLANs defined
VLAN 30 for Data VLAN
VLAN 31 for Voice VLAN
I have two Cisco 3750 switches.both switches are connected to IP Phones.the configuration of Cisco 6500 Trunk Port to Cisco 3750 is [code] On Cisco 3750, the trunk port to 6500 has the configuration [code].The IP Phones connected to the Cisco 3750 are 7911,7979, 7940, 7961.
All phone are working fine, the phones get their ip address from voice vlan, and systems connected to phones get from data vlan, except 7940/7960.
These two models of IP Phones remain on Configuring IP, and when you check the IP Settings, it gives Data VLAN IP, which does not have a TFTP.once you manually enter TFTP address in the field, it registers instantly, due to ip routing in the network.
these phones were working fine before, but suddenly few days back they went out of the network, and still are in Configuring IP state.I also tried to convert these ports connected to 7940/7960 to access ports [code] but still the IP is taken from the Access Vlan (30). Even If you configure a single VLAN on these ports, the IP phones then never get the IP.
have multicast data across OTV extensions? We run OTV between two pairs of Nexus 7000 in different datacenters with mcast underlying encapsulation. We stretch 10 or so vlans between the sites. We have encountered multiple bugs over the last two years and had to upgrade code and have rarely been clear for any period of time.
We've had an ongoing Tac case where IGMP requests are not getting across the OTV VLAN extension to the PIM forwarder on another site. You can see OTV IGMP snooping on the AED VDC is picking up the request on the local site but it does not get to the remote site that is the PIM forwarder so no multicast gets onto the VLAN. For a while we had a hack where we would get a local server to the PIM forwarder router to request the same groups and then this would somehow get across to the other site. Since clearing the overlay interfaces to try and fix the original problem the hack no longer works and I can't get multicast to the receiver at all.

View 1 Replies View Relatedim working in a new enviroment and want to makes some design changes to the environment. I wanted to bounce my ideas some of you folks to see if my thinking is on the right path or maybe i could do things better.
Setup:
Currently the setup that i manage includes and Sonic Wall (also dishes out dhcp), HP 1810 "Core Switch" and 3 SG 300-28P cisco managed switches. (all cisco switches tie back into the HP) The router is managed by the isp. There is only one vlan with all traffic going across it.
Obviously the glaring issue here is that voice and data all reside on the same vlan. Correct me if i am thinking incorrectly but the first step would be to create a separate vlan for the phones with its own IP scheme. currently phones are issued addresses from the 150-200 range and everything else is left for pc's, printers etc. To my knowledge the HP switch does layer 3 but i do not know much about it. There are vpn tunnels to remote offices that are used for sharepoint, email and to access other services. Trying to wrap my mind around the environment as a whole so i may be missing something obvious i could do design wise to improve.

Multicast is not working between our two datacenter, we have catalyst 2960S (two stacked) as the internal lan switch, and catalyst 3560E as the external switch, same configuration for both datacenters.The two sites are connected using metro, the external switch (3560) is doing qinq and encapsulate the data from the internal switch with the metro vlan (611).
IGMP snooping is disabled for all switches, although we prefer to enable it for the internal switches.For each datacenter there is a different firewall which also act as the router, we are using fortigate as the firewall.Following is the important configuration section:
Port 43 in the internal switch is connected to the external switch (both sites):
interface GigabitEthernet1/0/43
switchport mode trunk
load-interval 30
Port 3 in the external switch connected to the internal switch (both sites):
interface GigabitEthernet0/3
switchport access vlan 611
switchport mode dot1q-tunnel
no cdp enable
no cdp tlv server-location
no cdp tlv app
Port 8 on the external switch connected to the metro link (both sites) vlan 350 is the internet and 611 is the metro:
interface GigabitEthernet0/8
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 350,611
switchport mode trunk
vlan 611 on external switch:

Normally when we do HSRP with vPC on N7K the device will be Active/Standby in control plane but it will be Active/Active in data plane. In this case any traffic reach to standby device it can forward traffic directly to uplink which is not my desire. My goal is all traffic should pass through active (control plane) device in every case unless active device totally dead. So Is it possible for Nexus 7000 to be HSRP Active/Standby in Data Plane ?

I don't want the Cisco to do any NATting and there's no need for firewalling either.
We an 887m router in our office with an unmanaged switch. We have two networks, 192.168.0.x and 192.168.11.x connected to router on the same interface (192.168.11.253 is a secondary ip) but I can seem to be able to route packets from one network to the other. Internet traffic is fine from both networks. I can't see what I'm doing wrong here. I can ping the 192.168.11.253 (router) from the 192.168.0 network but nothing beyond that.
I tried this at home with no other config and its the same. Is this by design?
