Cisco Firewall :: 5520 - Object-group With Network-object Containing IP Address Range

Apr 7, 2013

Does the ASA treat an object-group with a network-object containing a range of IP addresses as a netmask? For example, I can apply this configuration without the ASA throwing any errors though the configuration calls for a 'net mask':
object-group network test
network-object-group mode commands/options:
A.B.C.D  Enter an IPv4 network mask
sh run ob id test
object-group network test
I found that in the documentation it requires a netmask as oppose to a range. Is this a bug in the code? I am running code version 8.0(5)23 on a 5520. If this is not a bug how does the ASA treat this type of configuration when applied to an access list? When I ran a quick packet trace and denied access from that range it looks like the ASA doesn't read that configuration properly.

Cisco Switching/Routing :: WS-C3560-24PS / WS-C3560-48PS - Port With WAP Goes To Err-disable?

Oct 11, 2012

We have a Cisco switch in each office and every now and then the port that has the D-Link Wireless AP (DAP-1522) connected to it goes to err-disable state. Actually sometimes even a regular port that has a cisco phone connected may also go to err-disable state (less often). So I have to telnet into the switch and issue shut and no shut command on that interface to get it back to life, then it works for a few days or weeks until it happens again. Any suitable configuraiton for that interface, that would prevent that from happening or a workaround ?
Here's the info:
Model: cisco WS-C3560-24PS and cisco WS-C3560-48PS
This is the log from one switch:

31w5d: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/2, putting Fa0/2 in err-disable state
31w5d: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address 74e2.f592.f7f2 on port FastEthernet0/2.
31w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed  state to down
And from another, which is almost the same:

5d10h: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/3, putting Fa0/3 in err-disable state
5d10h: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address d8a2.5e31.2cf6 on port FastEthernet0/3.
5d10h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/3, changed state to down
5d10h: %LINK-3-UPDOWN: Interface FastEthernet0/3, changed state to down
Here's the configuration of fe interfaces (they are all alike):

interface FastEthernet0/2

switchport mode access

Cisco Security :: ASA 5510 Object-group And Range Option

Feb 6, 2013

I have 3 ASA 5510s; two of which are in production and the 3rd one is new. I inherited the two in production and was trying to configure that 3rd one using some of the existing object-group network statements.  The problem is that when I try to create a range of IPs in one of the object-groups; the range command is not available. Here is one of the statements extracted from one of the production ASAs:  object network REMOTE range ASAs have the same image ver (asa842-k8).  Is there something that I am missing to be able to enable the range option on the new ASA?

Cisco Firewall :: Internet Access Through ASA 5540 For Specific Network Object Group

May 2, 2011

I have a 5540, and i am trying to allow access to internet for an specific network object group, who has inside a bunch of users, who needs direct internet access without any restrictions, i have tried with dynamic NAT, but that configuration ask for a specific IP o a Network range, and is not permitted to configure an  object group as a source
The group is located in LAN zone, so a permission from one zone to another zone is needed i think, but i can allow the internet acess to that group Is there another way to get that , different from NAT ?

the intent of the above is that management connections will only be accepted via SSH, and all of those will be authenticated via RADIUS, unless it's down, then it will use the local username/pw combinations, most of which are given Privledge level 15. Telnet should never work.SSH works as expected (authenticates via RADIUS), but the problem is that Telnet also works, will ONLY use the local database (never RADIUS), and, for some reason, leaves the users at Privledge level 1, instead of the configured 15.Essentially, it seems that at every point I have told it to do something that isn't the default with regards to telnet, it ignores me.Prior to a recent IOS upgrade, the switch didn't support SSH, so the previous config was Telnet with RADIUS, and that worked fine.

Cisco Switching/Routing :: C3560 Swap Out Not Ping Across Network

Jun 17, 2012

Had a switch die over the weekend, a c3560, per our normal procedure I pulled the hardware put a very basic config on it(vlans, portchannel, uplink ports, ip of management vlan, con and vty security, snmp, enable secret, and hostname).  Then I use solarwinds orion to upload a copy of the old config to bring the switch back to the same state as the one that failed.  Its a system that has worked for us 3 or 4 times in the past.  But this time when the base config was on the box it couldnt ping across the network.I have tried clearing the arp cache and the dynamic mac tables, i verified the routing tables and even removed the route and re-added it, saw the routing update go across to the other 65k, tried bouncing the edge switch(i cant bounce the 65k's), took down the po between the edge and 65k.

Cisco Switching/Routing :: C3560 Output Drop Without MLS QoS Enabled

Nov 24, 2012

We are seeing output drops on a C3560 switchport, this port does not have QoS enabled -- application does not need special qos treatment, as long as packets are not droppd, so I suppose all traffic will share the same queue? then how should I read the output of "show platform port-asic stats drop" which indicates that it is queue 3 weight 2 drop? I am wondering what is the best way to fix this? enable mls QoS and increase queue 3 bandwidth share on this interface or just increase the output queue depth?
switch#sh mls qos interface gi0/1
QoS is disabled. When QoS is enabled, following settings will be applied
trust state: not trusted

Cisco Switching/Routing :: WS-C3560-24PS - Rate Limit And QoS

Mar 4, 2012

I am having an issue with VoiP phones giving me an insufficient bandwidth message.  I have three remote locations connected to our main building using 2 Mb point to point ethernet solutions through TWC.  Each remote location has a Cisco WS-C3560-24PS running IOS C3560-IPBASE-M, version 12.2(25) and have the cable modems plugged into port 1 on them.  The remote buildings are labeled,, and  There are 14-16 VoiP phones in each remote building.  The main building being in the subnet of  I have the 3560s connecting to a single port on a 2801 in the main building, all using the subnet of  The phone server sits in our network at  I have created the ACLs, class maps, and policy maps on all of the equipment. 
For the remote buildings I have the following:
Extended IP access list VOIP
permit tcp any host dscp ef
permit tcp any host eq 5566


I have put a hub in to capture traffic via Wireshark to see if DSCP flags are being appropriately marked and I do see that all VoiP packets are getting marked with as EF.  However, I have been receiving phone calls from people in the remote buildings stating that their phones will cut out, flash Insufficient Bandwidth on the LCD displays and then the call will cut back in.  I am wondering if the 2801 is not applying QoS with the rate-limits in mind since it is set to 100 Mb, or is it an issue with trying to take 3 remote locations and bring them down into 1 port on the 2801?

Cisco Switching/Routing :: C3750 - Data Center / IP Routing

Feb 21, 2013

I 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.

Cisco Switching/Routing :: C3560-24P Spontaneously Rebooting When Clients Try To Print

Feb 19, 2013

I have a C3560-24P PoE switch, running on a very small network with nothing special about the endpoints or the configuration (5 laptops connecting via 1 wireless AP, 1 firewall uplink, a networked printer and one conference room phone using PoE.   That's it.)   I actually have inline power turned off on all the non-PoE device ports.
We are encountering a very strangle anomaly where if a client attempts to send a print job through the switch, to the network printer, the printer makes a noise as it if's begun to initialize and then the switch immediately goes into a reboot.   Also the reboot appears to immediately drain all he batter power from the UPS unit that it's connected to.   The unit is an APC SmartUPS 750 (500W, 750VA) and when the switch reboots the load on the UPS jumps to well above 100% until the switch appears to 'level out'.  Is that kind of power draw normal when rebooting a C3560?

Cisco Switching/Routing :: C3750 SFP Failure After Reload

Mar 11, 2013

I have a cable from an SFP module in a WS-C3750-48P with 12.2(55)SE1 running to a Gigabit port on a Cisco WLC. After the switch recovers from a power failure, the gigabit autonegotiation fails. The cure is a long drive to unplug and reseat the SFP. Note this happens at too many similar sites for this to be a loose connection. Interface shutdown then 'no shutdown' is not sufficient. The state is 'line protocol is down (not connected)'. Interface is configured for switchport mode trunk (auto speed, auto duplex). Command 'switchport nonegotiate' makes no difference. Is there a more powerful command than 'shutdown' which might toggle the interface signals? Is there some way of resetting the SFP? sh int gi 1/0/1 displays 'media type is 10/100/1000BaseTX SFP' and zero packets received.
