EXPANSION MODULE NOT RECOGNISED:
show chassis fpc pic-status # If this shows the expansion modules offline. request chassis system-mode flexi-pic-mode all-members # do this and reboot
CHANNELIZATION - BREAK OUT CABLES (fiber break-out):
- a colon is used to signify the four separate channels. Like xe-0/1/2:0, xe-0/1/2:1, xe-0/1/2:2, and xe-0/1/2:3
[edit chassis fpc 0 pic 1] set port-range 0 3 channel-speed 10g set port 3 channel-speed 10g # for one et port (4 10G channelized)
MC-LAG
https://jira.oracledatacloud.com/browse/SYS-5112
- Configuration with examples: External Link
- Static arp in vrrp (l3) mc-lag: External Link
- ICCP & ICL-PL in different links: External Link
- Inter-chassis Control Protocol (ICCP): It uses TCP as a transport protocol and requires Bidirectional Forwarding Detection (BFD) for fast convergence
- Interchassis link-protection link (ICL-PL) : Each ICL can learn up to 512K MAC addresses.

- To configure mc-lag:
- Active-active : External Link
- Active-standby: External Link
- To see status of mc-lag link External Link:
show iccp detail show bfd session detail show interfaces mc-ae

FOR TSHOOT:
set interfaces irb arp-l2-validate #turns on validation of ARP and MAC table entries, automatically applying updates if they become out of sync. Workaround when the network is experiencing other issues that also cause loss of ARP and MAC synchronization. Ddisable it during normal operation because this option might impact performance in scale configurations. show iccp show interfaces mc-ae show lacp interfaces show l2-learning redundancy-groups remote-macs show ethernet-switching table show ethernet-switching redundancy-groups remote-macs
OSPF PROTOCOL
To see the lsa we need to use 'detail' flag:
show ospf database router lsa-id 148.64.56.250 detail show ospf database external lsa-id 0.0.0.0 detail
EVPN AND VXLAN
MAC addresses conveyed via bgp. Datacenter. At the end of the day these are knobs to avoid using L3!. Listen to this podcast
- ESI—An Ethernet segment must have a unique nonzero identifier, called the Ethernet segment identifier (ESI). The ESI is encoded as a 10-octet integer. When manually configuring an ESI value, the most significant octet, known as the type byte, must be 00. When a single-homed CE device is attached to an Ethernet segment, the entire ESI value is zero. The Ethernet segment of the multihomed Device CE1 has an ESI value of 00:11:22:33:44:55:66:77:88:99 assigned. The single-homed Device CE2 has an ESI value of 0.
- EVI—An EVPN instance (EVI) is an EVPN routing and forwarding instance spanning all the PE routers participating in that VPN. An EVI is configured on the PE routers on a per-customer basis. Each EVI has a unique route distinguisher and one or more route targets.An EVI is configured on Routers PE1, PE2, and PE3.
PORT MIRRORING:
For local mirroring, the output interface needs to have an IP in the switch physical interface itself!!! Traffic will be coming encapsulated from that IP. So I really need a standalone monitoring station
#B05 (ae5 is connected to dmc02) set forwarding-options analyzer employee-monitor input ingress vlan 510 set forwarding-options analyzer employee-monitor output interface ae5.0 set interfaces ae5.0 family inet address 192.1.1.1/24
