Hi I have been trying to search for any documentation that could guide in configuring an SCE to look for authentication information via ACS RADIUS. Any ideas ? Also, does the SCE have a feature to provide a logon page for users to enter their credentials which are then cross-checked against the entries in ACS ? Apologies if I have posted in the wrong forum. Regards Vivek

Unfortunately, the ASA is not on a contract so upgrade is not possible. Are you able to provide any documentation to back up your theory ? And I don't think there is any issue between VSS MEC and ASA Redundant interfaces, however OSPF protocol seems to have one. I'm just not able to pin-point to the cause of this issue.

Thanks for replying Reza. I used the ON mode to create the etherchannel on the VSS and since the ASA that I'm working on has the 8.3.1 software on it, etherchannel is not an available feature. Etherchannel on ASAs was introduced in 8.4+ versions hence using Redundant interface. Hence my original question ?

Hi community, Does OSPF work between a VSS L3 MEC & an ASA Redundant Interface ? Physical Connections - 6509(Active) Port Gi 1/1/10 ------RJ-45------ Port Gi0/2 ASA 5520 v8.3.1 6509(Standby) Port Gi 2/1/10 ------RJ-45------ Port Gi0/3 ASA 5520 v8.3.1 Both 6509 are in VSS and a L3 MEC is formed to the ASA Both ASA ports are a part of a L3 Redundant Interface. Please note there is only a single ASA in this topology. Config - On VSS interface Port-channel 20 description **** MEC to ASA **** no switchport ip address 192.168.10.1 255.255.255.0 no ip redirects no ip unreachables ip ospf authentication message-digest ip ospf message-digest-key 1 md5 cisco <Both ports Gi1/1/10 & Gi2/1/10 are a member of this MEC> router ospf 10 router-id 192.168.10.1 log-adjacency-changes redistribute connected subnets redistribute static subnets passive-interface default no passive-interface Port-channel 10 network 192.168.10.0 0.0.0.255 area 0 On ASA interface Redundant 2 description **** To VSS **** member-interface GigabitEthernet0/2 member-interface GigabitEthernet0/3 nameif routing security-level 100 ip address 192.168.10.2 255.255.255.0 ospf message-digest-key 1 md5 cisco ospf authentication message-digest router ospf 10 router-id 192.168.10.2 network 192.168.10.0 255.255.255.0 area 0 log-adj-changes redistribute connected subnets redistribute static subnets default-information originate always Problem - Now, the OSPF neighboring does occur and go into the FULL state on this device, however soon enough, the state enters INIT/DROTHER state. But as soon as I disconnect the physical connection 6509(Standby) Port Gi 2/1/10 ------DISCONNECTED------ Port Gi0/3 ASA The OSPF adjacency goes into FULL mode. Any suggestions on where am I going wrong ? (there are no duplex or speed or cable issues) Thanks Vivek

EtherChannel load balancing (ECLB) is not supported between an IDSM-2 in the VSS active chassis and an IDSM-2 in the VSS standby chassis [ http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/vss.html#wp1138509 (read Service Module Restrictions and Guidelines, point #3) ].

Thank you for your comments Eugene & Joseph. JosephDoherty wrote: First, if your going shape traffic to 30 Mbps, you need to shape all traffic. Your parent's shaper is only defined in class-default; other classes could exceed the 30 Mbps limit. The physical interface has a limit placed on it as 30M bandwidth and so the bandwidth within the classes of "wan-qos" should come into effect and not send anything more than the 30M limit set of the interface. JosephDoherty wrote:
Forth, ideally you would want to shape all 4 Mbps for the branch, also using the above considerations, but if a 3 level hierarchy isn't supported, yours is good, but again because of strict timing considerations for VoIP, you want the child's shaper to use a small Tc too. For this configuration, you do want a separate child class for VoIP, but LLQ won't really trigger unless the child policy sees congestion at the parent's shaper.
All other branches have good bandwidth wan links except this particular branch which only has a 4m link. I think a 3-level hierarchy is supported on the WAN router. The only issue was I wasn't sure if my configuration was following the best pratice in terms of combining the QoS policies. So the way I have configured and combined the QoS policy, is that correct ? I'll research the tx-ring-limit and Tc values as well. Thanks Vivek

Hi Community, Scenario: HQ WAN Router already has a QoS Policy applied on its WAN port (30M link) [HQ has several branch sites and no issues with the rest of them except one branch. That one branch will be spoken about in this thread] Branch WAN Router is on a 4M link and has no QoS policy - voice traffic from HQ to Branch is getting affected. ISP QoS is not possible at this moment due to cost reasons Config: HQ WAN Router - Current interface GigabitEthernet0/1 service-policy output wan-qos class-map match-any mgmt match access-group name mgmt
class-map match-any ldap match protocol ldap
class-map match-any abcd match access-group 112
class-map match-any voip-signal match protocol skinny
match protocol mgcp class-map match-any voip-media
match protocol rtp class-map match-any rdp match access-group 111 ! policy-map wan-qos
class iccs bandwidth 1024
class voip-media priority 164
class voip-signal bandwidth 48
class rdp bandwidth 64 class mgmt bandwidth 16
class ldap bandwidth 32
class class-default
random-detect ! New QoS policy for HQ to Branch voice traffic ***** Classify Voice traffic to Branch ***** access-list 102 permit ip <HQ IP> <Branch IP>
class-map voice-branch-traffic
match access-group 102 ***** Giving voice traffic a guarantee of 200 kbps with a burst of ~ 20kbps ***** policy-map Priority-Voice-branch-Traffic class voice-branch-traffic priority 200 20000
***** Max traffic out to branch will be limited to 3.6Mbps (10% reserved) ***** policy-map branch-Traffic class class-default
shape average 3600000 service-policy Priority-Voice-branch-Traffic Now to apply this new QoS policy within the already current (wan-qos) of the HQ router, would the following way be correct ? policy-map wan-qos
class abcd bandwidth 1024
class voip-media priority 164
class voip-signal bandwidth 48
class rdp bandwidth 64 class mgmt bandwidth 16
class ldap bandwidth 32
class class-default
shape average 30000000 ----> HQ WAN Link is 30M (random-detect had to be removed to apply the policy) service-policy branch-Traffic ----> Shaping HQ to Branch Voice traffic to be less than 3.6M
Is this the correct way to apply the new "branch-Traffic" QoS policy under the existing one "wan-qos" on the HQ router ? Regards Vivek

hmm that could very well be the problem because I took the product id from the show version of the switch which needed the IOS upgrade. Instead I should have looked for the product id on the chassis. Good find. I may get another batch of switches to upgrade so if I do, I'll try it out again and report into this thread.

Hi Julio, You don't need to do the test. The issue was with my switch. I have changed it with another switch and it works now. So the end user certainly doesn't need to be connected directed (logically) for cut through proxy to work.

Seems like it may only work when a direct connection to ASA is available. When you get a chance try to create an SVI on the L2 switch and see if you change the test pc gateway to be the L2/L3 switch IP, does the authentication prompt comes up or not.

Hi Julio, I tried the same setup with a c3750 and the findings are the same. If the laptop's gateway IP is set to the SVI of that VLAN on Switch - no auth prompt If the laptop's gateway IP is set to the ASA inside interface - auth prompt comes up So not really sure whats happening here. Could you kindly inform me of your lab setup ? Thanks Vivek
