Cisco Switching/Routing :: Ping Break Between ASA 5550 / 2911 (directly Connected Via Ethernet)

Aug 15, 2012

we have the following setup for our network :
 
UserNetwork - ASA5550 - WAN Router 2911 - ISP Netowrk - Branch Routers 877s / 1941s
 
Since last week we started noticing this problem that the branch users started to complain of slow application response.. After verifying it with the ISP and middle network we noticed that if i ping from my machine (ie usernetwork) to the WAN Router interface (facing the ASA) , i get time outs..  which is strange cause this is directly connected to it via ethernet cable.

Cisco Switching/Routing :: 3560 / ISR 2911 - NAT Of Network That Is Not Directly Connected

Dec 1, 2011

I have a CAT 3560 connected to a ISR 2911 The 3560 has 2 subnets ( 192.168.1.0 /24 and 10.10.10.0 /24)  The 2911 has interface GigabitEthernet0/1 on the 192.168.1.0 /24 and another GigabitEthernet0/0 on a WAN connection 172.16.7.246 I need to NAT both the 192.168.1.0 /24 and the 10.10.10.0 /24 to the single address 172.16.7.246 I have to use route-maps .  I have IPSec VPN's and ZBF on the 2911 My problem is the NAT does not work for the 10.10.10.0 /24 network!Why?is my only option to use trunking  between the 3560 and 2911 and subinterfaces on the 2911? I want to avoid sub-interfacing.

Cisco WAN :: 2800 Can't Ping Directly Connected Devices

Mar 28, 2013

I'm trying to configure a 2800 series router. .I'm consoled in and put a basic config on the router (see attached). After putting this basic config on, I plugged it into a small unmanaged switch, changed my laptop's IP and plugged it in the switch also. I can't ping the router from the laptop and vice versa. This is the second switch I've tried this with, so it must be.The first switch, I installed at location, connected a cisco cable to it and a local server, so i could remote in and finish configuration. In that scenario, I had plugged the switch into a managed switch and had the same result as I'm getting now--can't ping IP addresses (can't ping the switch's IP, not can it ping local IPs).

Cisco Switching/Routing :: VPC Pair Of Nexus 7K And Servers Connected Directly

Jan 9, 2012

My Data Center has one single core switch where is connected several servers, one port is the link to the router wan and other port is the link to the FW, my boss wants to install 2 nexus in order to replace the single switch. All my network has only one address, for example 192.168.10.0/24 if I connect two nexus 7010 in VPC and Domain, each nexus is going to has 2 modules with 48 port 10/100/1000 rj45 and i wan to connect servers directly to each nexus, with this figure i'm going to have a group of servers connected in two different nexus, Do they can have the same network 192.168.10.0/24 considering that the nexus are in the same vdc and vlan and have only one gateway for both groups? If the answer is positive, which nexus would be the gate way for that address, the primary or secondary? Or i must have a different address for both group of servers, i mean for example 192.168.10.0/24 and 192.168.12.0/24?thus each nexus would be the gateway for that new address?
 
To have two nexus connected by VPC in a Domain mean that one computer connected to one nexus can share the same address or vlan with other computer connected to the other nexus????

Cisco Switching/Routing :: 3750X - VTP Not Working With Switch Not Directly Connected

Sep 9, 2012

We have a 3750X VTP Server and the rest of the switches are clients.
 
Due to cabling issues, we have a switch (Switch F) that we can't connect directly to the 3750X so we have it connected through another switch. Everything is set to VTP client with the correct domain and password but this not-directly-connected switch isn't receiving any VTP VLANs.
 
Anything I need to do on Switch D so that Switch F can receive the VTP updates?

Cisco Switching/Routing :: 3750 Receiving CDP Packets From Switches Not Directly Connected

Jun 27, 2010

A specific switch port which happens to be part of a 2 switch 3750 Switch Stack is seeing multiple CDP packets from 3 extra switch port interfaces that are not directly connected. Noteworthy is that the far end devices have the correct CDP entries and I physically confirmed at least two of those connections that lead to the switch "upstream to the culprit switch". Tricky part is that its production so room for maneuvering is limited. At some point I disabled all Ports save for the real uplink and the problem momentarily disappeared. Re-enable the interfaces problem resurfaces. Is there an explanation, technique to eliminate the culprit with minimal disruption?

Cisco Switching/Routing :: 7206VXR - WCCP Redirection Of Non-directly Connected Subnets

Jul 18, 2012

I have a Cisco 7206VXR running 12.4(24)T3 IOS. It is configured with WCCPv2 using L2 mask redirection. I am using service groups and associated extended ACLs to select which subnets I want to redirect port 80 traffic from.
 
It is working fine for the subnet 192.168.1.0/24....
 
int gi0/2
ip wccp 10 redirect in
ip address 192.168.1.99 255.255.255.0
  
... however, there is OSPF running between the router and a Mikrotik device directly connected to this interface. The gateway addresses for all the client subnets are on the Mikrotik. Traffic from other subnets, e.g. 192.168.2.0/24, 192.168.3.0/24 come in on this interface and I want to redirect those too. But it appears that the redirection doesn't work for those subnets (I don't see any hits on the relevant ACL for any subnet except 192.168.1.0/24).
 
It seems like the router only wants to redirect traffic for subnets that it has an IP address in itself. Admittedly, all of the example configs i've found on cisco.com are for redirecting traffic from directly connected subnets but I can't find anything that denies thie possibility of redirecting any traffic that comes in on a given interface.
 
The question is, is this how WCCPv2 redirection works? i.e., the router must have an IP address in the subnet to be redirected?

Cisco Switching/Routing :: 2911 - Unable To Ping On Other Device

Sep 20, 2012

I cannot ping and end node on my system from my Cisco 2911. I've tried to configure my computer to ping the device and I am able to. It seems the difference between using my computer and the 2911 is that with my computer I am able to set the default gateway as the end node's ip.

Cisco Switching/Routing :: 2911 / Can't Ping Windows Servers In Different VLANs Through SG 200-50

Jul 18, 2012

last week I installed a new router (2911) in my network.We had to create two different VLANs for the new setup to work as wanted.I have a Windows 2008 R2 which is a Domain Controller for Active Directory on the ip address 192.168.0.195.That server (HP DL180 G6) has two NICs. One has the above IP address and the other one has 192.168.0.199.
 
On the other VLAN, I have a server, running the same OS, that I want to re-join, as it formerly was, the AD on the first server (192.168.0.195). This server has the new IP address 192.168.10.194.All these are connected to a Cisco switch SG 200-50 Gigabit Smart Switch. That one is connected to a Cisco 2911 router.
 
The problem is that, once the old 192.168.0.194 got to be 192.168.10.194, the 192.168.0.195 can't ping it anymore... At least not all the time... Sometime it works, sometimes not... Neither can't the 10.194 ping the 0.195 all the time. When one way works the other one doesn't... When one pings the other one successfully, the other one can't...

Cannot Ping Modem Even Connected Via Ethernet Cable

Apr 22, 2011

A friend recently re-installed windows XP on their HP Laptop. They were connected wirelessly with a Linsys router (model wrt54g.1) and an RCA Cable Modem. The Cable ISP can ping the modem and gave me the IP address over the phone. I cannot ping the modem even when I take the router out of the loop. The network card (i1394) in the Laptop is functioning normally and I can see traffic on the modem (both the Cable Internet light and the PC activity light are flashing green) the ethernet port on the laptop is also flashing (amber). However I cannot reach the internet and cannot even ping the modem. The modem is brand new..

Cisco Switching/Routing :: Filter A Specific Host(s) From OSPF Routing Table On A ASA 5550 (ABR)?

May 22, 2013

I am attempting to filter a specific host(s) from my OSPF routiing table on a ASA 5550 (ABR) using LSA prefix lists.  However, when I look at the other routers in that area, I notice that ALL LSA type-3's are being removed (10 hosts are now missing from the routing table). I have verified the filter is working on the ABR, but I can't figure why ALL hosts/routes that were coming into the area are now being filtered instead of the specific one that I want to filter out.
 
Here is the config on the ABR:
 
prefix-list pdm_pl_000 seq 10 permit 206.253.180.137/32
!
!            
router ospf 1
network 10.0.0.0 255.255.255.0 area 0
network 10.150.10.0 255.255.255.0 area 10
network 10.150.252.0 255.255.255.224 area 10

[code]....
 
The 206.253.180.137 host is actually coming from Area '3'.  Am I doing something that is removing all type-3 LSA's?

Cisco Firewall :: NAT To IP Address Not Directly Connected To PIX 515

Mar 27, 2012

Can an ip address be NAT'ed to an ip address on a PIX 515 which isn't an ip address of a network directly connected to an interface on the PIX?
 
Specifically, can a host with an ip address of 150.140.102.3/26 which is connected to a network whose PIX firewall interface is 150.140.102.1/26 be NAT'ed to an ip address of 150.90.70.1/24 which is not a ip address of an interface that is directly connected to that same PIX 515?
 
I've attached a PDF depicting the network topology and describing the above.My first response to this question is that it can't be configured to do this, but need either a confirmation or correction to this.

Cisco Firewall :: ASA 5550 - Cannot Ping SITE 1 PIX From Internal IP

Oct 15, 2012

We have two networks HQ and Site1 and for some reason we can’t ping the inside IP for Site1 PIX device. We have site-site-VPN set up between the two and everything works fine except we can’t ping the Site1 PIX from internal IP. However, I can ASDM/SSH in from HQ to the external IP of the Site1 PIX. 

HQ is using an ASA 5550 (172.1.0.1) PC from HQ (172.1.64.x) Site1 is using a PIX-515E (172.2.0.1) PC from Site1 (172.2.64.x)
Ping from HQ PC to Site1 PC (172.1.64.x to 172.2.64.x) works fine
Ping from Site1 PC to HQ PC (172.2.64.x to 172.1.64.x) works fine
[code]... 

ASDM/SSH from any HQ PC to Site1 PIX internal IP (172.1.64.x to 172.2.0.1) doesn’t work
ASDM/SSH from any HQ PC to Site1 PIX external IP (172.1.64.x to Site1 external IP) works fine
 
Everything was working fine until we recently changed the outside IP address for Site1 because we switch to a different ISP. Nothing changed on the HQ ASA or Site1 PIX other than the outside IP address on Site1 PIX. I did rebuild the site-to-site VPN tunnel between Site1 and HQ.

Cisco Switching/Routing :: 3560G Can Ping Devices In Enterprise LAN But Cannot Ping Interface

Mar 31, 2012

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

Cisco Switching/Routing :: Can Ping From R1 To R3 SVI4 Gateway But Cannot Ping Host

Dec 12, 2011

I set this up and I can ping all the gateways but never the hosts.  I was hoping I could make these links between 6500's a mix of L2 and L3.  Check it out.  They are connected in a linear fashion R1--->R2--->R3.  I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4.  I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration.  I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

Cisco Switching/Routing :: Layer 3 Switch And ASA 5550

I created a lab and I have a few issues. One with a layer 3 switch and another with a ASA 5550.
 
1. Layer 3 switch: I have created multiple Vlans and I am able to route between them. I can ping the switch IP but not the default gateway to the ASA. I did a tracert of the default gateway of the ASA and once I am past the Vlan gateway it fails.
 
2. On the ASA 5550 I created the Vlans on sub-interfaces but still cannot get to the internet. ASA config is below the switch config.

Cisco Switching/Routing :: Checking Internet Speed Directly In The 1841 Router?

Nov 2, 2011

I want to know is it possible to check Internet speed directly in the cisco router thru any command or activating any service in the cisco router?.As it is seen most of the times internet speed offer by ISP is different as compared to clients.and Clients most oftenly not satisfied with internet speed The problem is that our ISP has given us 100MB leaased line.But when we deployed in production network the speed is same as DSL.We have reported this issue to ISP they then carried out Iperf test by connecting laptop directly with the ISP router.They have tested the speed and it shows  about 94-96 Mbps and argu that it is up to the mark and there is problem at your side(i.e our internal network).Now our internal network has cisco 1841 router connected directly to ISP 3825 cisco router.Our router has minimum configuration as required to pass traffic out and in.Our internal 1841 router is connected to switch to which different clients are connected.We have performed some online tests using different speed checking websites and also perform real time tests by uploading and downloading files.The speed is much low as compared to 100Mbps and it is nearly or slightly higher then as DSL connection. how can we check internet speed in the specified scenario?Is there any command or service available in cisco router to check internet speed as we want to check ISP connection speed directly thru 1841 router?what about authenticity of online speed checking websites?Any specialize software/tool you recommend to check Internet speed in specified scenario?

Cisco Infrastructure :: 2 6509-E Switches Connected Directly To Each Other While Using VRF-lite (Sup 2T)?

Apr 11, 2013

I am trying to test (if possible) the idea of having 2 6509-E switches connected directly to each other while using VRF-lite (Sup 2T). The idea is to have 3-4 separate networks. For example Net-A, Net-B,Net-C, Net-D. There is no PE router*, just these two switches. Also, there sin't any other access layer switches. All users connect directly to the 6509-E's via switch 48 port switch blades.  
 
Net-A and Net-B on separate VRF's, but able to talk to each other. Net-C and Net-D* on separate VRF's without being able to talk to any other. Net-D* will have a PE since it comes from an external network. This is something I would like to test in a lab environment, but I am not familiar with VRF's.
