890 Apr 23 01:57:56 : Path strict_br3.lax9 instance id 3 received path-error from Error code 4, Error value: 0:No sender information for this RESV message

got a clue from this article link

2) The biggest problem I experienced in RSVP was because of a strange issue. Egress router J35 had multiple IP addresses on its mpls facing interface. This caused RESV message to be sent
from an IP address that J35 isn’t expecting. I saw that once J35 received this RESV, it returned an RESV error message “no sender information for this resv message“.  I fixed it either removing extra IP addresses or setting primary/preferred options on the primary IP which is the RSVP neighbor address.

on br3.lax9

interface ve 67
 ip router isis 
 ip address
 ip address
 no ip redirect
 ip mtu 9000
 ipv6 enable
 ipv6 router isis
 isis ipv6 metric 1
 isis metric 1

I removed the secondary IP address and the lsp came up

Quick Configuration Guide

Console port settings: 19200 bps N-8-1, no flow control
A lot of people mess up here because usually the console uses 9600 instead of 19200 baud

default username admin & password admin123

Setting up the RFS6000 you only need to hookup the WAN1 or uplink port. I didn’t use the management port.

Configure Management Vlan, IP Address, Name Server and Default Route on both controller and AP
config t
switchport mode trunk
switchport trunk native vlan
int vlan x (where x = management vlan)
ip address x.x.x.x/x
ip name-server x.x.x.x
ip route x.x.x.x
commit ***Must commit before changes take effect
wr mem ***Must save (wr mem) to save changes to flash

If you are not using VLANs then you can leave the interface in access mode and just configure ‘int vlan 1’

Go to web gui and configure the rest.

Setup the RF domain -> Timezone and country
Setup NTP server

Add AP to controller
on ap web gui go to adoption and add the controller IP there. save & commit.

Create wifi profile
add ssid and set bridging mode to tunnel
select the vlan that will be used for the wireless clients. The vlan and VE must be setup on the controller.

go to security select wpa or wpa2 then enter preshared key.

Add wifi profile to radio interface
create or use existing profile for AP device. go to interfaces -> radio. Add wifi here.

save & commit

users should be able to join the wifi network now. note you won’t be able to get an ip if you have no dhcp setup.

setup dhcp
configuration -> services -> dhcp server policy
create policy here.
add dhcp policy to controller. configuration -> services

The following commands had to be added:
lldp tagged-packets process
lldp med network-policy application voice tagged vlan 50 priority 0 dscp 0 ports ethe 1/1/1 to 1/1/48
lldp advertise vlan-name vlan 50 ports ethe 1/1/1 to 1/1/48
lldp run

this post above is missing some ACL rules


cisco doc

route was stuck in ospf database even though it wasn’t assigned to any routers. had to filter the route from being accepted

[email protected](config)#ip access-list standard route-filter
[email protected](config-std-nacl-route-filter)#deny
[email protected](config-std-nacl-route-filter)#permit any
[email protected](config-std-nacl-route-filter)#exit

brocade decided to deprecate sntp somewhere along the upgrade path to 5.3b and so ntp configuration was changed. ntp was not synchronizing at all and when i run ‘show ntp status’ it displayed panic mode

Brocade# show ntp status
Clock is unsynchronized, no reference clock
NTP server mode is enabled, NTP client mode is enabled
NTP master mode is disabled, NTP master stratum is 8
NTP is in panic mode

to remove panic mode:

Brocade(config)# no clock summer-time
Brocade(config)# no clock timezone us pacific

set the utc time. Jan 31 20:07:06:A:NTP: NTP is in panic mode. Please set the clock manually within 1000 seconds of current time.

Brocade# clock set 17:40:00 04-11-12

wait for ntp to sync in the syslog. this part took a while.

Oct 17 12:44:01:I:NTP: Stratum is changed to 3.
Oct 17 12:44:01:I:NTP: System clock is synchronized to

reconfigure timezone and dst

Brocade# config terminal
Brocade(config)# clock timezone us pacific
Brocade(config)# show clock
09:41:27.182 Pacific Wed Apr 11 2012
Brocade(config)# clock summer-time
Brocade(config)# show clock
10:41:35.632 Pacific Wed Apr 11 2012

i also had racl(receive access-list) enabled so i had to add the ntp server to the acl

ip receive access-list 155 sequence 5
access-list 155 permit ip host host

and set the source-interface in ntp configuration. my full ntp configuration below:

disable serve
source-interface loopback 1
server pool.ntp.org minpoll 4


this route was stuck in ospf

[email protected]#show ip ospf route

Destination Mask Path_Cost Type2_Cost Path_Type 2 0 Intra
Adv_Router Link_State Dest_Type State Tag Flags Network Valid 0 3000
Paths Out_Port Next_Hop Type Arp_Index State
1 v234 OSPF 65535 8a 00

but this router wasn’t even advertising the route!!!

[email protected]#sh ip ospf route

Destination Mask Path_Cost Type2_Cost Path_Type 2 10 Type2_Ext
Adv_Router Link_State Dest_Type State Tag Flags Ase Valid 0 1800
Paths Out_Port Next_Hop Type State

so i added the route /29 to a ve and removed it to reset the routing table!
