The LMS 4.0.1 keeps sending ICMP messages to VLAN interfaces that have been removed months ago.these logs are filling up my log server [code] How do I update the poller to use the latest config information for the switch?
View 1 RepliesIs there a way or software can I use to send messages to all wirelessPCs in my network without doing any configurations or installation on those PC.I've used net send command for that, but is there another way?

log in to the internal buffer : buffer size 1048576 bytes
Then i save the buffer to FTP server to save the log messages in continuously way everything was working fine but suddenly sending the ftp traffic to FTP traffic has stopped suddenly before in the live log viewer it was showing when ASA throws the ftp traffic to the ftp server but this stopped suddenly nothing has changed in the ftp server setting (same username and password and the connectivity is there) sending logging traffic to the ftp server came back just when i reboot the ASA.but this is not solution.
Today I run into a problem with enabling ICMP traffice between two inside interfaces on ASA5510 (version 8.2). I tried to ping from 192.168.1.2 to 192.168.2.2 Failed. But I can visit outside websites or ping from any of the two addresses above to 8.8.8.8 So I checked the configuration shown as follow
<omitted>
interface ethernet0/1
nameif inside
[Code]....
I have set up an ACL on my 3750 switch to deny icmp from PC A on our inside network to PC B on a different VLAN on our inside network using the following ACLs:
deny icmp host 10.1.17.15 host 10.3.10.4
deny icmp host 10.3.10.4 host 10.1.17.15
-- or --
deny icmp host 10.1.17.15 host 10.3.10.4 echo-replydeny icmp host 10.3.10.4 host 10.1.17.15 echo-reply
These ACLs belong to an access-list that also limits ip traffic to a few specific machines.When I try pinging from PC A I receive a reply message back from PC B. Shouldn't this configuration block any ICMP from PC A to PC B and from PC B to PC A? I would have expected the first ACL statement to block any packets associated with ICMP and when that didn't work I tried the second configuration.
I'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 am using an Old 3500XL and I simply created a
interface VLAN 100
Description ***********
ip address 10.0.1.100 255.255.255.248
no ip directed-broadcast
no ip route-cache
shutdown
no matter what I do i cannot get it to come up, the rest of the switch is default config, I know I am just forgetting something, But I don't know what?
This is for an ASA 5505 with the base license...I have a situation where I will not have one interface in my outside VLAN, but instead I want to have interfaces 1-7 in my outside VLAN and interface0/0 in my inside VLAN.
Is this supported with the Base license, and if so how would I do this? Do I still just need to assign one IP address to the outside VLAN?
Or will I need to upgrade to the Security Plus license and put each interface in a separate outside VLAN, so in essence I would have 7 outside VLANs each with the same security level (0)?
My situation is that I have several partner networks that i want to "aggregate" thru my one ASA 5505. So each outside interface represents a separate partner (outside) network, each of which I want to get to from my inside network. Hence the many outside to one inside.
How can i enable Netflow for each Vlan Or interface indvidually in Cisco ASA? currently i have setup Netflow and only 2 interfaces are shwoing traffic for Netflow which are not even as my physical or Vlan interfaces . (see screen shot )

View 1 Replies View Related I'm having some trouble getting my head round the following but I think it's routing related?
I have a Cisco 3750 switch with the following configured:
interface Vlan1
ip address 192.168.0.223 255.255.254.0
no ip route-cache
[Code].....
The 3750 is connected to a firewall which handles the routing. From the 3750 I can only ping remote networks from the vlan1 interface not from vlan6,8 or 10 i.e ping 10.34.37.101 (remote network) source 192.168.0.223 (vlan1) works but ping 10.34.37.101 source 10.74.10.1 (vlan10) does not? I can ping 10.34.37.101 from computers on the various vlans but not from the 3750 it self.
I looked at setting a default gateway for the various vlan interfaces
I cannot seem to ping between devices on two networks hanging off a 5520 unless I use the same-security interface command. I have the relevant ACL's set up between the interfaces, but it just doesnt work unless I have that command in - if I use that command, it bypasses the ACL.

View 1 Replies View RelatedMore and more recently I'm seeing that inspect ICMP and ICMP error do not allow trace route to work through the firewall from inside to outside.I used to go in, enable the inspections and subsequent trace route's worked. Now when this is enabled, the firewall still blocks return trace route.
View 4 Replies View RelatedI'm new to the Cisco WLCs and recently implemented a wireless infrastructure using a WLC 2100 with 1262 LWAPs. I have two of the 1262s plugged into ports 7/8 using crossover cables. They're functioning correctly with the exception of the inability SSH and send pings to the LWAPs behind the WLC. Is there anyway to ping/shh through the WLCs to the LWAPs behind it? I use an NMS (Nagios) to monitor the status of the LWAPs and it can't monitor them if it cannot ping them. Also, is there anyway to configure the WLC to monitor the status of LWAPs?

View 4 Replies View RelatedHave a very peculiar issue with IP SLA. Firstly, the architecture.
1) There are two sites - A & B. Both have their own internet connection.
2) Sites A & B are connected via MPLS.
3) Both sites have the below topology.
3750 CORE --> FIREWALL -->ROUTER ---> INTERNET
4) 3750 has a Default route pointing to firewall .
5) MPLS router is connected to 3750. A default information is originated via BGP to MPLS at each location. So that default route is learnt as a backup path from any location if it has to lose its local internet.
6) IP SLA has been configured at each location to track the default route using icmp-echo to hit a public IP (i.e 4.2.2.2 as an example).
Issue?ICMP probes from Site-A via its local internet fails abruptly. I can reach the public IP mentioned above from my firewall pretty fine, but not from my 3750. Whenever i remove the tracking from the static default route & push in the plain default route without tracking, it works fine. Again, if i add the tracking back, it will work fine for an hour or so & then fails back again. To my bad, Site-B had recently gone offline due to some natural calamity. So, there is no other path for internet.
My config looks pretty simple
track 10 ip sla 1 reachability
!
ip sla 1
icmp-echo 4.2.2.2 source-ip 10.1.254.1
frequency 180
ip sla schedule 1 life forever start-time now

So I have my shiny new (used, but new to me) 5510 finally working and installed in my Dev network. I need to have icmp (ping and trace route) available from the inside network. I Google and found a few articles on how to do it. I tried modifying the class maps, but it looks like there are changes in the commands in 8.4 and the articles I found evidently were for 8.2 and lower. I tried doing it with access lists, again from examples and traffic stopped in all directions (not good) so I am back to being functional and how to do it in 8.4. Documentation seems sparse on the net with 8.4

Recently, the Syslog is no longer displaying any records (neither new or old messages).
Below are the steps I have tried to troubleshoot the problem:
- Installed wireshark : Syslog messages are being received by the LMS server on time
- In the Syslog.log file, I can see that all the Syslog messages are being logged properly
- I tried to disable all the "Syslog Message Filters" but nothing changed
In the SyslogCollector.log, I can find the below logs:

I have a small problem with a lot of invalid syslog messages in LMS 3.2. Something about 30% of all messages are invalid.
Is there any posibility to get out from which devices those messages are?
Is it a big problem for the application if there are such a lot of invalid messages? I have a lot of devices in my LMS and don't want to get high load because of such unneeded messages.
