Cisco WAN :: ASR1002 Dynamic NAT Entries Are Not Released

May 31, 2012

we are using an ASR 1002 for dynamic NAT (with route maps). I do have a Problem with the usage of the NAT pool it self.The total NAT Translations for the pool are:

#sh ip nat stat
[Id: 1] route-map natted-host-01 pool nat-pool-01 refcount 136
pool nat-pool-01: netmask
start XX.XX.202.0 end XX.XX.203.255
type generic, total addresses 512, allocated 88 (17%), missee 0
If i now look into the NAT translation Table i do get less entries:
#sh ip nat translations filter map-id dynamic 1 total Total number of translations: 43
Only a deeper look into the QFP gives here the right values:
# sh platform hardware qfp active feature nat data The ouput count matches the values I get if i isue a sh ip nat stat
My question is how is it handled internally.
We do have a problem too, with raising usage of the pool over the time.Once allocated Pool entries are not released after a period of time. And no NAT translation occur for that used IP NAT pool Addresses.
The timer on the device are set:
ip nat translation timeout 300
ip nat translation tcp-timeout 900
ip nat translation pptp-timeout 900
ip nat translation udp-timeout 120
ip nat translation routemap-entry-timeout 900
ip nat translation max-entries 750000

Cisco Application :: ASR1002 / ESP2 / Getting Error Log When Change Redirect ACL Entries

Aug 7, 2011

I've configured WCCP2 on my ASR1002/ESP2 and works fine. But got error log since I changed redirect ACL entries. Check on Cisco seems it a known bug?[URL] And seems any change on WCCP not take affected anymore. Even I removed all WCCP configure on my router, but my cache engine still got the redirected packet!?

Cisco Switching/Routing :: 3750 IP Addresses Are Not Being Released From Table

Feb 21, 2012

we have a 3750 and use dhcp services on the switch.  every so often we run out of ip's even though we have  much less users than the size of the allocated dhcp pool.  I've noticed that the dhcp bind table is full but a ping-sweep only shows very few ip's being assinged and used.  It looks like the IP addresses are not being released from the table even though I have decreased the lease time to 8 hours.

Cisco WAN :: ASR1002 IOS Upgrade From 2.x To 3.x?

May 29, 2013

Right now I have a ASR1002 running a very old IOS version.Cisco IOS Software, IOS-XE Software (PPC_LINUX_IOSD-ADVENTERPRISEK9-M), Version 12.2(33)XNE, RELEASE SOFTWARE (fc1) asr1000rp1-ipbasek9. – 25-NOV-2009?
I am looking to upgrade to a newer version.I was wondering if there are any tricks when upgradeing this IOS. Is it as easy as loading the IOS onto the ASR and then changing the bootpath or is there an upgrade path I must follow? Also would there any need for a licence between 2.x and 3.x.

Cisco WAN :: ASR1002 - Inspection Of ACL Hits

I'm aware ACL's are handled in hardware on the ASR platform but wondered if there was any way to inspect how many hits we get on each line of an ACL on the ASR, I can't seem to find a command to do this.
Using LOG is not possible due to the large number of hits.

what command is required to configure ip accounting on an interface?
I would have thought to what is required is on the interface, turn on Ip accounting i.e.

ip accounting
However, there is no ip accounting command within the interface.  We are running version Version 15.1(1)S2.

Cisco WAN :: ASR1002 With Full Bgp Table(s)

Jun 19, 2011

I've inherited a project building an internet connectivity solution for a large corporate. It has its own AS and its own PI space. They are putting in 100Mbit connections from 5 different Tier1's , taking full internet routing from each. Cisco ASR1002's have already been specified and purchased for the job. I'm not familiar with the ASR platform at all - is it up to the job with full routing tables? multiple instances of full tables ? (not likely to put all 5 into one box!)

Cisco Firewall :: 15.2 / How To Interpret IOS Log Entries

Oct 12, 2011

how to read some of these log entries I see on the IOS 15.2 router I'm working with.  I'm fairly new to this stuff.  My understanding is that the first socket ( is the originating one, and the 2nd socket is the receiving or destination.  This makes sense when I see an entry like:
01043: *Nov 21 2012 10:28:34.323 PCTime: %FW-6-DROP_PKT: Dropping tcp session xx.xx.241.163:39557 192.168.xx.xx:80  due to  RST inside current window with ip ident 0
The internal IP is our email server inside the LAN, the first IP is some IP in a foreign country, so someobody visited our web interface for the email server, obviously trying to breach or recon the interface but whatever.  Then I see an (unrelated) entry like this elsewhere in the logs:
001095: *Nov 21 2012 25:56:03.531 PCTime: %FW-6-DROP_PKT: Dropping tcp session xx.xx.178.210:25 192.168.xx.xx:47343 on zone-pair inside-outside class INSIDE-OUTSIDE due to  Stray Segment with ip ident 0
What this latter entry tells me is that the Internet host sent data FROM port 25 to what I am guessing is the open port our internal email server must have originated some other communication from.  However we do not accept incoming port 25 mail from anywhere but a designated IP so this "send" is not supposed ot occur.  So first off, am I reading that correctly?  Is the first IP the sending system, and the second IP the receiver?   there are no other entries in the logs between these two hosts, so either the logs have truncated with oldest entries removed (log buffer is set to 51200), or that outside host is sending, hoping to get our mail server to respond?  BTW, the outside host WHOIS's to Microsoft's IP range, Block 1.

Cisco WAN :: ASR1002 / 1006 SFP Compatibility With SPA Module?

Aug 15, 2011

I am trying  to bring up a couple of ASR's. They are fitted with SPA modules (SPA-8X1GE-V2). These have SFP modules GLC-T fitted into them. For the life of me I cannot get these ports to come up. If I have a look at the inv the SFP's show as GE-T's (physically they are GLC-T's)
Is there a compatability problem with these GLC-T's on ASR 100x?

Cisco WAN :: ASR1002 - Licensing Not Supporting Any Device

Jun 30, 2011

I have recently purchased ASR1002-RP1-ESP5 with 2 x 4K Broadband licenses to be used as LNS. Cisco have sent me PAK files for the licenses however when I try to enter the licenses into the device I get an error message saying that Licensing is not supported on this platform.
Any experience with this platform and installation of the broadband licenses?
When I spoke to Cisco TAC they told me that for this particular model the licensing is on "trust" basis where you buy license and do not install it on the actual router - similar to what 7200 used to do.

Cisco WAN :: Management And BITS Ports On ASR1002

Aug 30, 2011

We recently purchased a Cisco ASR1002 router with four on-board Gigabit SFP-style Ethernet ports. However, when I do a "show ip interface brief", I see that there's an extra Gigabit Ethernet port. See the last interface in the following output:
ASR_1002_router#sh ip int b
Interface                         IP-Address       OK?     Method Status          Protocol
GigabitEthernet0/0/0       unassigned      YES  manual     down                down

On the router itself, in addition to the four Ethernet SFP ports, there are four additional RJ-45 ports. They're labeled "BITS", "MGMT", "CON", and "AUX". I know what the Con and Aux ports are, but what are the Bits and Mgmt ports? And is one of them the Gigabit Ethernet interface that I see listed at the bottom of the output? And if it is, is there anything special about it, or is it just another routed Ethernet port? Can I do something special with it, like out-of-line managment?

Cisco WAN :: ASR1002 Running SubPackages And IOS Vulnerability?

Apr 19, 2012

We have ASR1002 routers configured to run individual SubPackages, at this point everything is operating without problems.We just received a Cisco Security Advisory informing us SSHv2 is vulnerable in our version of router code.We have to upgrade to the recommended stable release, so we downloaded, installed and expanded the IOS to expose the SubPackages on the ASR routers bootflash.

Since we are running SubPackages, do we need to upgrade all SubPackages (I.E. complete IOS upgrade) of can we just upgrade the vulnerable SubPackage? How do you determine which SubPackage contains the SSHv2 application?
