[Contents] [Prev] [Next] [Index] [Report an Error]

JUNOSe software uses 128-byte buffers.

The egress memory available for queues available depends on the ASIC and the line module. Table 5 lists the egress memory.

Table 5: Egress Memory and Region Size on ASIC Line Modules

ASIC	Line Module	Egress Memory (MB)	Region Size (MB)
EFA	All EFA line modules	32	4
FFA	GE-2 and GE-HDE	64	8
	OC48	128	16
	ES2 4G LM	128	16
TFA	ES2 10G LM	96	12
