View 2 RepliesI have aaa new model configured on a number of isr's(1800, 1900, 2900, 3800 etc). When i have aaa configured, the telnet logins use that authentication and not the password in the line vty portion. Is this by design. would disabling aaa enable both telnet and aaa authentications, essentially making it a dual login.

It does not have an access list bound to the outside interface. This is working fine, but i am wondering if this is a security concern?

View 2 Replies View RelatedI've just started out playing with a Cisco 1800 router to gain some knowledge of Cisco devices before taking a CCNA. I also have a 2950 switch but will start with the router.
I'm using an Android phone as a wireless Internet access point. This issues IP addresses by DHCP in the 192.168.43.x range with 255.255.255.0 subnet.
Also I have a Linksys WRT54G router running DD-WRT firmware acting as a wireless bridge to the Android phone, and it has 4 LAN ports.
This bridge is up and running and I have successfully connected my laptop to the Linksys for testing and can use the Internet provided by the phone.
Connected to the Linksys is a Cisco 1800 router. Connected to the router is my Citrix XenServer PC and a NAS box.
The XenServer and NAS are on another network 07.05.19.x range with 255.0.0.0 subnet using their own static IPs. One of the virtual clients on the XenServer will be a DHCP server to service other virtual clients. All still in the 07.05.19.x range.
Basically I want the devices on the 07.05.19.x IP range to be able to use the Internet gateway at 192.168.43.1 to access the Internet.
How would I set up my 1800 to achieve this?
Also, am I right in understanding that the 1800 will ignore DHCP leases from the Android phone due to it being a Layer 3 device.

We have some ME3800MX router/switches running ME380x-UNIVERSALK9-M), Version 12.2(52)EY2. The Cisco website says:
The switch does not support these Cisco IOS router ACL-related features: # •Non-IP protocol ACLs (see Table 26-1) or bridge-group ACLs
how we would match ICMP traffic then?
Both regular IP traffic and ICMP traffic are passing through the source port. C6509 provides the option of filtering vlan traffic during monitoring. But I don't have vlan traffic.
qa-c6509-c(config)#monitor session 1 filter ? vlan SPAN filter VLAN
So I applied an access-list which only allows icmp traffic to be sent out of the monitoring port. But it does not work.
I ran autosecure on my 1841 routere and now I cant do ping or traceroutes. What should I do to enable the pings and traceroutes after auto secure is done.

In some cases I receive normal response when pinging from one Nexus, but no response when pinging from the other switch. In other instance I receive normal response to one Nexus, and duplicate replays to the other. It looks like a VPC related bug. NXOS is 5.1.3.N2.1

I am in the process of installing a 3750x (IOS 12.2 (53r) SE2 IP Base) Cisco Catalyst switch in a new network of just 2 PC's (2 hosts, OS windows7 64Bits). I have enabled SVI interfaces with the both hosts installed in 2 different network segments. We then start connectivity test. The response time for the PING command between both hosts remain below 1 millisecond, whereas the response time between the hosts and their correspondent SVI interface is variable, and at all time is higher than 1 millisecond, sometimes it reaches 17 milliseconds. (Note that the switch CPU usage is only 8% at the time of testing) We have performed this same connectivity test changing the 3750x switches and in two different locations obtaining the same results.
View 2 Replies View RelatedI've a big problem with a loss of packets ICMP sent by different hosts in differents VLAN. Here my architecture:
Core Switch : 2 Switch's C6509 (Version 15.0 (1) SY1)- Mode VSS - One lien VSL , the other link is defective.Access Switch: C3750 , Connected to Core Switch through 2 fibre optique wires.Topology: redundant ring
When I send consecutive ping message I found always a missing of packets . Furthermore When I insert the "show ip traffic" command., the parameter "bad hop count" increase after a loss of packets. I've 2 hosts connected in my network and they send packets with TTL =127.
In the Core Switch I haven't configured the MEC because it gave me troubles with the packets multicast.
I had setup a lan infrastructure with 5 3750 stack swithes. In these 3 of them are in one stack which is acting as access switch, 2 of them in another stack which is as core switch where all the SVI is configured. Now, when i tried to ping from our edge pc which is connected in access switch to default gaeway, which is configured in core switch, the ICMP is getting delayed . But when try to ping from the same edge pc to another user PC, it is getting less tahn 1 millisecond icmp replies.
why icmp is delaying to default gateway , but working with another edge to edge pcs without any delays?
Need to clarify if ip sla icmp echo operation is supported in catalyst 3kx switches (ip services)? on the configuration guide, commands are available, but on the feature navigator, i can't find the feature, only ip sla video operation. i don't have a device to test on here.
View 2 Replies View RelatedToday one of our 9 Cisco switches a "WS-C2950S" (we also got 2 other WS-C2950S on same network) stop responding icmp ping packages. When i tried to telnet the switch its network was unreachable but i was able to see its existance from other switches by "sh cdp neig". So i decided to fix the situation on a suitable night time work, checking by console cable or even rebooting the device.
Then i started to wonder... what this could possibly be about?We have like 40 clients behind that switch and there was no communication problem during the problem.
i am facing a problem when the client vlan is commmunicating with the default gateway on the core 3750-x.
ios in 3750-x core is 3750e-universalk9-mz.150-2.SE.bin. But, client to client communication is happening without any dealy and icmp is less than 1 ms always.
When try to ping default gateway of client vlan, it is getting delayed (variable icmp delays). Is this an ios bug?
I have a cisco 2811 router set up as a nat/firewall gateway for my network. I've configured it for CBAC on using ip inspect and an access list.What I want is to use audit-trail to record network traffic (which means sending syslog messages to a server) concerning established sessions from my own network to locations in the outside. If i configure this using ip inspect audit-trail and no ip inspect alert-off, the configuration looks like this: [code] which works just fine, but there is the matter of icmp packets.
Since i use polling software that needs to check some machines in the outside part of the network, it is only natural that several icmp sessions are established through the Inspection Rule per minute. The problem is that since these sessions are recorded along with everything else, my syslogs are flooded with these (since i am using logging trap informational) to the point that more messages are generated about icmp than all other traffic combined, especially in non-working hours.What I am asking is a way for the audit-trail to be selecively disabled for icmp, so that the outgoing (echo) &incoming (echo reply) sessions can be established without generating syslog messages.
I have made some test and i noticed that qos input policy does not classify the icmp packet based on their dscp.The "match dscp ef" or "match precedence 5" is not working only the "match protocol icmp" shows hits.
We need to classify the different icmp packets based on dscp ( TOS ) for measurement purpose.CISCO 7200, 12.4.25d and 12.4.20T have a same behavior.
As the thread title says, I just want to gain better understanding by practising the config.

The scenario is this.
I have 3 ip net from the ISP:
178.249.51.0/255.255.255.248 Gateway 178.249.51.1
178.249.51.8/255.255.255.248 Gateway 178.249.51.9

I am also wondering - when we get more public IP net from the ISP, is this the correct way to do it?
I try to setup a ASA5510, but without success. Actually, I have Cisco1800(192.168.96.1/21) from my ISP connected to a Cisco 3825 (via port with IP 192.168.96.2) all is working good. Now I want to insert a asa firewall between ISP router and 3825.
For that, I tried a more simple config :
ISProuter (192.168.96.1/21) ---- ASA outside port(192.168.96.2/255.255.255.248) ASA INSIDE port (192.168.100.1/255.255.255.0) --- a pc with IP 192.168.100.2, netsmask 255.255.255.0, gateway 192.168.100.1
From my ASA, I can ping 192.168.96.1. but a "ping INSIDE 192.168.96.1" fail
from py pc, can ping 192.168.100.1, but not 192.168.96.1

upgrading our small office network. We currently have about 75 employees with probably 125 devices on the network. I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?
View 4 Replies View RelatedIn our datacenter we have a 3750 stack with IP base image. I have enabled PBR and reloaded the switch. Show sdm prefer says i am using default template. The reason i want to use PBR is that we have 2 firewalls on the same work and want to be able to have granular control over which gateway out of the network they use but still be able to access all internal resouces accross wan and locally.
Created access list to identify traffic:
access-list 10 permit 10.2.3.59 (test workstation on vlan 3)
Created policy:
route-map TestASA permit 10
match ip address 10
set ip next-hop 10.2.0.3
Assigned policy to the user vlan3:
ip policy route-map TestASA
Results:It changed the default gateway to the above gateway but i could not access any resources on any other vlan, could not access resouces accross wan.
The layer 2 switches are connected to layer 3 Switch via trunks, and routing between layer 2 switch ports with configured SVI's on 3550. All working fine. Now I'm trying to configure routing between 2800 and 3550, I tried connecting both Straight Throught and Crossover cables to the 2800 Fa0/0 and Fa0/1 ports as well as the switchports on 3550
No switchport commands are configured however, the lights do not go on for both straight through or crossover cables. I tried connecting 1750 routers but same result. My goal is to have all the VLANS routed to the internet with configuring NAT translation the router.
how do i configure the new asa 5505 to be as a router as shown in the diagram note: the isps' routers placed in head office. but i cannot change the configurations of the isp's routers.

If I have an ASA 5520 with an INSIDE interface, a DMZ interface and a WAN interface what would be the best way to configure NAT? If I configure nat-control and a nat (inside) 1 0.0.0.0 0.0.0.0 this will configure everything to be NAT'd when passing from the INSIDE interface out.My question is what about the devices I want to access in the DMZ from the inside for management etc? I'm guessing the ASA isn't smart enough to realise you're accessing hosts in it's DMZ interface so do you have to configure a nat 0 rule for every subnet within the DMZ you want to access or is there an easier way to do it? It's worth noting that the same devices will be accessing the OUTSIDE network and the DMZ network from the INSIDE network.
