Cisco Security :: MTU Size GRE Tunnels 6509
Nov 13, 2011I've created a Tunnel between a Cisco 2811 router and a Switch 6509, the tunnel works fine. However, I would like to run Multicast down this tunnel to avoid using a non-supported 3rd party network device that doesn't support multicast. Some of the multicast packets are above 1500 bytes. I would like figure out why the 6509 tunnel does not support frame sizes over 1500 bytes and the 2811 router does. I have applied ip mtu 1576 but this does not really come into play as the packets are UDP. problems seen below:
See the difference with MTU sh int tunnel1 - why is this
Switch config (s72033_rp-IPSERVICESK9-M), Version 12.2(18)SXF13)
interface Tunnel1
ip address 10.210.183.14 255.255.255.252
ip mtu 1576

Nov 27, 2011What is the impact of disabling xlate in FWSM
We have dynamic NAT configured from inside to outside interface, but still it is showing NAT entry as below.
"NAT from inside:177.26.99.10 to outside:177.26.99.10 flags Ii"
Expected NAT entry should as below :
"NAT from inside:177.26.99.10 to outside:111.111.111.111 flags Ii"
We were considering implementing "ip verify revert-path" .Hence here i am thinking whether xlate-bypass is the issue here and implementing same with "ip verify revert-path" woud be a good idea.
Cisco Switching/Routing :: Impact Of ACL On C6509 CPU Utilization?
Apr 4, 2012We plan to implement a large number of ACL on our Distribution switch which is a HSRP pair of 6509C switches running on sup-bootflash:s72033-psv-mz.122-18.SXD3.bin WE need to divide the Network in three layers
unsecure layer
Proxy layer
Secure layer
We have approximately 250 vlans on the our distribution switches and plan to implement 15 ACL on different vlans Each ACL can contain upto 30 lines or less.
basic ACL example we will be applying on different vlan
vlan 200
ip access-group test123 in
My question is Can these ACL on a vlan can have a massive impact on the 6509 CPU ?
Cisco Wireless :: 4941 Impact Of Incorrectly Set Antenna Gain
Jul 7, 2009What is the impact of incorrectly setting the antenna gain on a the b/g radio of an AP would have on a WLAN?
I've come across a site where around a 3rd of the AP's had their antenna gain set to 0. I can only assume that something missed setting this during setup. The site uses 1242ABG AP's and each has 2 4941 antennas and i believe the gain should be set to 4 x 0.5dBi

View 4 Replies View RelatedCisco Switching/Routing :: Impact Of Deleting And Creation Of SVI Interface On PBR 6513
Apr 22, 2013I have a query regarding the deletion and creation of one of my SVI interface on 6513 ,The reason behind it as follows.My traffic get to Internet in this manner
proxy(external int.)[IP:192.168.1.30] --> Gi0/9[6513 in VLAN 170] --> SVI VLAN 170[IP:192.168.1.10] --> Gi0/10[In VLAN 170] -->ASR[IP:192.168.1.20],I need to assign this VLAN ie 170 to my inside interface of firewall but it was mentioned in books like this "Assign the VLAN for the FWSM before it is applied to the MultilayerSwitch Feature Card (MSFC)." so I am thinking the following steps to assign VLAN 170 to firewall group first before creating SVI Interface for it
1.Remove all currently assign ie Gi 0/9 & Gi0/10 interfaces from this VLAN and then delete this VLAN.
2.Create the same SVI ie VLAN 170[IP:192.168.1.10] by this way the issue can be resolved.
As in part of my configuration PBR is define like this .
interface Vlan170
description "PUBLIC IP VLAN"
ip address 192.168.1.20. 255.255.255.0
ip policy route-map NAT
route-map NAT permit 10
match ip address 101
set ip next-hop 192.168.1.10
I need to clearify what impact it may have on PBR part if I delete and create the VLAN 170.Will the traffic move to the inside interface of FWSM.

I recently erased flash and loaded the latest asa841-k8.bin version of IOS along with asdm-642.bin. Everything booted fine and came up as it does when freshly wiped however I noticed that i was now only running a base license. If I issue the sh activiation-key command, I noticed the following messages (full output is at the bottom):
